If the potential difference across a 12 -ohm resistor is 4 volts,what is the current through it? 0.3 A 0.5 A 3A 4A

## Step 1The problem involves the application of Ohm's law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor. The formula for Ohm's law is:### where is the current, is the voltage, and is the resistance.## Step 2In this problem, the voltage is given as 4 volts and the resistance is given as 12 ohms.## Step 3Substitute the given values into the formula:### ## Step 4Calculate the current .
