Your car battery is a 12 V DC source. Typically you might find a fuse that can handle a 5 amp surge. What resistance is that fuse protecting?

2.4 ohms

Explanation:

From the question,

Applying ohm's law,

V = IR Equation 1

Where V = Voltage of the car battery, I = current, R = resistance

Make R the subject of the equation

R = V/I Equation 2

Given: V = 12 V, I = 5 amp.

Substitute these values into equation 2

R = 12/5

R = 2.4 ohms
