Question 82583: If P is power (in watts) and R is resistance (in ohms), then the voltage V necessary to run the circuit is V=√PR
Find the voltage necessary to run a 40-watt amplifier with a resistance of 150 ohms.
Okay I set the problem up and did the work. Did I get it right?
V=√40*150
V=√77.45966
V=38.72983

You can put this solution on YOUR website!
V=√(40*150)
V = sqrt(6000)
V = 77.46
