The maximum power rating of a 20 ohm resistor is 2 kW. A DC source of negligible internal resistance and
emf V volts is connected across the resistor. What is the maximum value of V so that the heat produced
does not melt the resistor?
Pls answer, the first to give answer will be marked as brainliest!!!!

Answer:
power P= v i = v^2/R
2000= v^2/20
v=200 volts
