Question

The current and voltage in a circuit is given by:

Answer 1

The Voltage, V(in volts), across a circuit is given by Ohm's law: V=IR

Where I is the current (in amps) flowing through the circuit and R is the resistance (in Ohms). If we place two circuits, with resistance $R_1$and$R_2$, in parallel, then their combined Resistance, R, is given by

$\frac{1}{R}=\frac{1}{R_1}+\frac{1}{R_2}$
