Video- Ohm’s Law-Voltage, Current and Resistors in Parallel Circuits

by Editor on November 18, 2011

Resistors in parallel. This video from Dunwoody college shows a parallel circuit which has 2 possible paths for the flow of electricity to take.

It shows how you can use a Ohm’s Law and a table to calculate the total resistance and current in each resistor a parallel circuit.

This is Ohm’s Law.

V= IxR  or  I=V/R  or R=V/I

Ohm’s Law deals in the relationship between Voltage (V or E), Current (I) and resistance (R).

When you know 2 of the parameters helps you find the 3rd missing one.

For example, if you know current and resistance you can find out the voltage.


Rules For A Parallel Circuit

Voltage is constant to each resistor

Total current is the sum of current flowing through each resistor

Total resistance is always smaller than the smallest value resistor
