# Ohm’s law Example # 1: Find Current through 2.2 kiloohm Resistor when input is 12 V source

Statement: A 2.2-kiloohm resistor connects to 12 V source. Using Ohm’s wheel find the current flowing through the circuit.

The circuit diagram:

In our present case, we are interested to find the current. The basic formula V = IR will be used.

I = V/R = 12 V / 2.2 kΩ

= 5.45 A
