Question

a 12 volt car battery pushes charge through the headlight circuit resistance of 10 ohms. how much current is passing through the circuit?

Explanation:

Step1: Recall Ohm's Law

Ohm's Law is \(V = IR\), where \(V\) is voltage, \(I\) is current, and \(R\) is resistance. We need to solve for \(I\), so we can rewrite the formula as \(I=\frac{V}{R}\).

Step2: Substitute the given values

We are given \(V = 12\) volts and \(R=10\) ohms. Substituting these into the formula \(I=\frac{V}{R}\), we get \(I=\frac{12}{10}\).

Step3: Calculate the current

\(I=\frac{12}{10}=1.2\) amperes.

Answer:

\(1.2\) amperes.
