Solve the following automotive-services problem based on the examples shown previously:

Voltage = 12V
Current = 48 amps
Resistance = ?

Answer :

We understand than automotive electricity is based in a direct current system, so we can apply Ohm's law, which says R = V/I, where R is resistance, V is voltage and I is current.

R = 12 / 48 = 0.25 Ohm
Resistance = 0.25 Ohm
