# Current

In a parallel circuit, current will be different in each branch. The total current of the circuit (the current coming out of the power source) will be equal to the sum of the current in each branch. This means that current coming out of the power source will equal the sum of the current running through the 220-ohm resistor branch and the 330-ohm resistor branch.

Let's look at this with Ohm's law to see how this works. To calculate current with Ohm's law we use the formula I=V/R, which means the current equals the voltage divided by the resistance. Earlier, in the resistance section, we calculated that the resistance in the circuit was 132 ohms and we know that the voltage is 9 volts, therefore, the total current will equal 9 volts/132 ...
