If you have a parallel circuit with a battery (4 ohms), a light bulb (2 ohm), and a fan (3 ohms), how would you find the total resistance of the circuit? 1/R=4+1/2+1/3
R = 4 + 2 + 3
R=1/4+1/2+1/3
1/R=1/4+1/2+1/3

Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source. You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +...
