Variable Resistor In Series Circuit. The figure below shows a resistor in a series circuit composed of two resistors. They can also be used to control the voltage across devices in a circuit too.
I frac v r s frac 9 v 90 omega 0 1 a. N resistors in series combination each with different resistance will have n different potential differences across them. Features of the series circuit.
As the resistance increases in the variable resistor the current through the circuit decreases and vice versa.
A series resistor circuit is shown in the below figure. R1 4 ω r 2 4 ω r 3 2 ω r 4 2 ω r 5 3 ω and dc battery 15 v then. Features of the series circuit. The current through the circuit is the same for each resistor in a series circuit and is equal to the applied voltage divided by the equivalent resistance.
