a circuit has a resistance of 2.5 ω and is powered by a 12.0 v battery. the current in the circuit, to the nearest tenth, is a.
Answer
Explanation:
Step1: Recall Ohm's Law
Ohm's Law is $I=\frac{V}{R}$, where $I$ is current, $V$ is voltage, and $R$ is resistance.
Step2: Substitute given values
Given $V = 12.0$ V and $R=2.5$ $\Omega$, then $I=\frac{12.0}{2.5}$.
Step3: Calculate the current
$I = 4.8$ A
Answer:
$4.8$
