on a simple circuit, how much current flows from a 2 volt battery through a 5 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 values

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

Step3: Calculate current

$I = 0.4$ amps.

Answer:

$0.4$
