  • about resistors - 2205 Words
    What is a Resistor? An electric resistor is a two-terminal passive component specifically used to oppose and limit current. A resistor works on the principle of Ohm’s Law which states that voltage across the terminals of a resistor is directly proportional to the current flowing through it. Ohm’s,Law: v=IR where V is the voltage applied across resistor, I is the current flowing through it, and R is the constant called resistance. The unit of resistance is ohms....

    LDR Circuit Diagram: Here is the schematic for the circuit: Light Dependent Resistors Light Dependent Resistors (LDR) are also called photoresistors. They are made of high resistance semiconductor material. When light hits the device, the photons give electrons energy. This makes them jump into the conductive band and thereby conduct electricity. A photoresistor or light-dependent resistor (LDR) or photocell is a light-controlled variable resistor. The resistance of a photoresistor...

    Factors affecting the resistance of a wire Introduction: Resistance is a force, which opposes the flow of an electric current around a circuit. Resistance is measured in Ohms. George Ohm discovered that a circuit sometimes resists the flow of electricity. He called this 'RESISTANCE.' He even came up with a rule for working out the resistance of a circuit, which was: R= V ÷ I V- Volts I- Current R- Resistance Ohms law says the more resistance means more energy is needed for the current to...

The circuit is highly efficient as it uses thyristors for power control. Alternatively, the same circuit can be used for automatic temperature controlled AC power control. In this circuit, the temperature sensor used is an NTC thermistor, i.e. one having a negative temperature coefficient. The value of thermistor resistance at...

    In this lab, we were given an LED nightlight circuit. Upon first glance we noticed all the components, the zener diode, 3 resistors, a capacitor, 4 diodes, a photocell, an LED light, and something we thought was a transistor. We knew the first thing to do was to identify all of the components and find out the rating for them. We had to use the microscope to determine the identifying numbers on the zener diode, the capacitor, and the, assumed, transistor. The zener diode read 1N5242B,...

    Introduction I have chosen to investigate a factor that affects the output of a potential divider circuit. A potential divider is resistors connected in series across a voltage source; used to obtain a desired fraction of the voltage. A resistor is a device having resistance to the passage of an electric current which affects the output voltage (Vout). The factors that I could investigate are changing the resistance of r2 and record the output (Vout), or use a light-dependent resistor (LDR) and...

Ohm's Law shows the relationship between the voltage (V), current (I) and resistance (R). It can be written in three ways: V = I × R or I =V/R or R = V/I The resistance (R) of a material depends on Its length, cross-sectional area, The resistivity, and Resistance also depends on temperature,...
