PLS HELP I WILL GIVE THE BRAINLIEST ANSWER

Ohm's law states that $V=IR$ for a simple circuit, where $V$ is the total voltage, $I$ is the amount of current running through the resistor and $R$ is the resistance of the resistor. If $I=40$ amperes when $R=3$ ohms, find the amount of current (in amperes) when the resistor has a resistance of $20$ ohms. Assume voltage remains constant.

Answer:

6

Step-by-step explanation:

If V = IR, then V = 40 * 3 in this case, which means V = 120. Quote question, "Assume voltage remains constant." This means V still equals 120 in the second scenario, which we can input into I = V / R to make I = 120 / 20 = 6.

Hope this helps!
