If a current is two amps and the resistance is 3 ohms, how much voltage was needed?

Hunter-Best [27]

Answer:

6 V

Explanation:

We can solve the problem by using Ohm's law:

$V=RI$

where

V is the voltage in the circuit

R is the resistance

I is the current

In this problem, we know the current, $I=2 A$ , and the resistance, $R=3 \Omega$ , therefore we can find the voltage in the circuit:

$V=RI=(3 \Omega )(2 A)=6 V$
