A commerical resistor can safely dissipatepower only up to a cetain rated value.

Question

   A commerical resistor can safely dissipatepower only up to a cetain rated value. Beyond this value, theresistor becomes excessively hot and often cracks apart Theresistor used in this experiment was rated by the manufacturer tobe a 2 watt resistor. What is the largest voltage that cansafely be applied across the resistor? Hint: The powerP dissipated by a resistor Ris givne by P = I2R =V2R = IV where I is the current and V is thevoltage.    A commerical resistor can safely dissipatepower only up to a cetain rated value.

Explanation / Answer

We have the power rate of the resistor is P =V2/R then the maximum voltage can be applied to the resistor is V =(PR)                                                                                           = (2R)
