Question

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

Answer 1

6 V

Step-by-step 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`
