Asked by San
A commercial resistor can safely dissipate power only up to a certain rated value. Beyond this value, the resistor becomes excessively hot and often cracks apart. The resistor used in this experiment was rated by the manufacturer to be a 2 watt resistor. What is the largest voltage that can safely be applied across the resistor? Hint: The power P dissipated by a resistor R is given by P = I2R = V2R = IV where I is the current and V is the voltage.
