what is resistor - how it works - how to check the resistor value

Resistor

Resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element.

In electronics circuits , resistor are used to reduce current flow , adjust signal levels , to divide voltages , bias active elements , and terminate transmission lines , among other uses.

High-power resistors that can dissipate many watts of electrical power as heat may be as part of motor controls , in power distribution systems , or as test loads for generators .

 Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity.

• resistor value can be checked by using color code
• and also can be checked by using multi meter
• for begineers multi meter is very useful

What is diode and how its work - simple circuits and tutorial

Diode

A diode is a device which only allows unidirectional flow from positive direction to negative direction.

A diode only blocks current in the reverse direction while the reverse voltage is within a limited range otherwise reverse barrier breaks and the voltage at which this breakdown occurs is called reverse breakdown voltage. The diode acts as a valve in the electronic and electrical circuit. A P-N junction is the simplest form of the diode which behaves as ideally short circuit when it is in forward biased and behaves as ideally open circuit when it is in the reverse biased. Beside simple PN junction diodes, there are different types of diodes although the fundamental principle is more or less same. So a particular arrangement of diodes can convert AC to pulsating DC, and hence, it is sometimes also called as a rectifier. The name diode is derived from "di-ode" which means a device having two electrodes. Its also used to convert from AC to DC current.

Types of Diode

The types of diode are as follow-

1. Zener diode
2. P-N junction diode
3. Tunnel diode
4. Varractor diode
5. Schottky diode
6. Photo diode
7. PIN diode
8. Laser diode
9. Avalanche diode
10. Light emitting diode

Simple circuit for diode:

             

how to check that the diode is working or not:

• Using multimeter we can check the diode
• if the multimeter display any value then the diode is working condition
• and some thersold values are there to check the diode is working properly or not
• below picture shows that how to check the diode

555 timer - how its works - simple and easy tutorial

555 timer

Pin	Name	Purpose
1	GND	Ground reference voltage, low level (0 V)
2	TRIG	Output of the timer totally depends upon the amplitude of the external trigger voltage applied to this pin.
3	OUT	This output is driven to approximately 1.7 V below +VCC, or to GND.
4	RESET	A timing interval may be reset by driving this input to GND, but the timing does not begin again until RESET rises above approximately 0.7 volts. Overrides TRIG which overrides THR.
5	CTRL	Provides "control" access to the internal voltage divider (by default, 2/3 VCC).
6	THR	The timing (OUT high) interval ends when the voltage at THR ("threshold") is greater than that at CTRL (2/3 VCC if CTRL is open).
7	DIS	Open collector output which may discharge a capacitor between intervals. In phase with output.
8	VCC	Positive supply voltage, which is usually between 3 and 15 V depending on the variation.

The IC 555 has three operating modes:

1. Bistable mode or Schmitt trigger – the 555 can operate as a flip-flop, if the DIS pin is not connected and no capacitor is used. Uses include bounce-free latched switches.
2. Monostable mode – in this mode, the 555 functions as a "one-shot" pulse generator. Applications include timers, missing pulse detection, bounce-free switches, touch switches, frequency divider, capacitance measurement, pulse-width modulation (PWM) and so on.
3. Astable (free-running) mode – the 555 can operate as an electronic oscillator. Uses include LED and lamp flashers, pulse generation, logic clocks, tone generation, security alarms, pulse position modulation and so on. The 555 can be used as a simple ADC, converting an analog value to a pulse length (e.g., selecting a thermistor as timing resistor allows the use of the 555 in a temperature sensor and the period of the output pulse is determined by the temperature). The use of a microprocessor-based circuit can then convert the pulse period to temperature, linearize it and even provide calibration means.

Bistable Mode :

circuit diagram for bistable mode

The 555 timer in bistable mode is also known as a flip-flop circuit. A flip-flop circuit alternates between two stable states, in this case the output of electrical current from the output pin. This is a fairly basic 555 timer circuit and unlike monostable mode and astable mode, it does not depend on a resistor and capacitor to set the timing of the circuit. In fact there is no timing in this circuit. There are only two stable states (on and off) controlled directly by the trigger pin and reset pin.

monostable mode:

circuit diagram

This is the circuit diagram of 555 Timer wired in Monostable mode. 8th pin and 1st pin of the 555 timer are used to given power Vcc and Ground respectively. 4th pin is the Reset pin of 555 Timer, which is active low so it is connected to Vcc to avoid accidental resets. 5th pin is the Control Voltage pin used to provide external reference voltage to internal comparators. Since it is not used here, it is grounded via a capacitor C’ (0.01µF) to avoid high frequency noises. When a negative trigger is applied on the Trigger input of 555, output goes high and capacitor starts charging through resistor R. When the capacitor voltage becomes greater than 2/3 Vcc, ouput goes low and capacitor starts discharging through the Discharge pin of 555 Timer. Time period of the unstable state is given the tye expression, T = 1.1RC.

Astable mode :
circuit diagram

The astable configuration, with two resistors, cannot produce a 50% duty cycle. To produce a 50% duty cycle, eliminate R1, disconnect pin 7 and connect the supply end of R2 to pin 3, the output pin. This circuit is similar to using an inverter gate as an oscillator, but with fewer components than the astable configuration, and a much higher power output than a TTL or CMOS gate. The duty cycle for either the 555 or inverter-gate timer will not be precisely 50% due to the fact the timing network is supplied from the devices output pin, which has different internal resistances depending on whether it is in the high or low state (high side drivers tend to be more resistive).it will create 0 and 1's pulse rate as output.

IRF830 traic - how it works_tutorial

IRF830

1) It's a type of transistor only 

2) Its mainly used for dimming the ac appilances

    for eg light,fan...

3) i dont want to explain deeply ,it will confuse you

4) pin(1) gate is a trigger pin ,when the trigger pin       is triggered by some minimum voltage either by       audrino's analog pin using ic(4n32) or some             other optocoupler.

5) the triac will activated .

6) the property of IRF830 ,drain(2) is a negative            pole and source(3) pin is a positive pole.

7) but the circuit is connected by negative for               source(3) and positive for drain(2).

8) because the traic will not make a closed loop           when there is no power supply(by its oposite           pole).

9) i done a dimmer light circuit using IRF830
