Question

A 12-volt car battery pushes a charge through the headlight circuit with a resistance of 8.5 ohms.how much current is passing through the circuit

Answer 1

Answer:

= 1.41 A

Explanation:

Using the Ohm's law;

V = Ir

where V is the potential difference or voltage

I is the current in Amperes and

R is the resistance in Ohms

In this case; V = 12 V, I = ? and R = 8.5 Ohms

I = V/R

 = 12/8.5

 = 1.41 A
