Question:

A manufacturer of carbon-film resistors specifies a maximum working voltage of 250 V for all its ¼-W resistors. Exceeding 250 V causes internal arcing within the resistor. Above what minimum resistance will the maximum working voltage be exceeded before its ¼-W power dissipation rating is exceeded? The maximum voltage that produces the rated power dissipation can be calculated as
