Question

rory uses a battery to power a light bulb with a resistance of 10 ω. if 0.15 a of current is flowing, what is the voltage of the battery?

Explanation:

Step1: Recall Ohm's law

$V = IR$ (where $V$ is voltage, $I$ is current, and $R$ is resistance)

Step2: Substitute given values

$I = 0.15$ A, $R=10$ $\Omega$, so $V=0.15\times10$

Step3: Calculate the voltage

$V = 1.5$ V

Answer:

$1.5$
