If the voltage in the circuit was 6.0 V with current of 2.0 A. What is the resistance?

3.0 ohms (Ω)

Explanation:

Ohm's Law states that Current (I) = Voltage (V) / Resistance (R)

I = V/R

If we rearrange this equation, we get an equation for resistance:

R = V/I

Plug in your values and we get:

R = 6.0 V / 2.0 A = 3.0

The unit for resistance is the ohm (Ω), so the final answer is 3.0 ohms!
