select the correct answer. how much current is in a circuit that includes a 9.0 - volt battery and a bulb with a resistance of 4.0 ohms? a. 0.44 amps b. 36 amps c. 2.3 amps d. 13 amps

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: Identify given values

$V = 9.0$ volts, $R=4.0$ ohms.

Step3: Calculate current

$I=\frac{V}{R}=\frac{9.0}{4.0}=2.25\approx2.3$ amps.

Answer:

C. 2.3 amps
