on a simple circuit, how much current flows from a 5 volt battery through a 2 ohm resistor? amps

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 $V = 5$ volts and $R=2$ ohms. Substitute into the formula: $I=\frac{5}{2}$.

Step3: Calculate the current

$I = 2.5$ amps.

Answer:

$2.5$
