Question

a wire with a resistance of 20 ω is connected to a 12 - v battery. what is the current flowing through the wire?

Explanation:

Step1: Recall Ohm's Law

Ohm's Law is $I = \frac{V}{R}$, where $I$ is current, $V$ is voltage, $R$ is resistance.

Step2: Substitute values

Given $V = 12\ \text{V}$ and $R = 20\ \Omega$, so $I = \frac{12}{20}$.

Step3: Calculate current

$I = 0.6\ \text{A}$.

Answer:

0.6
