1. A 100-kΩ resistor has a power rating of 0:25 W. Find the maximum current that can flow through the resistor.
2. A certain type of film resistor is available with resistance values between 10 Ω and 100 MΩ. The maximum ratings for all resistors of this type are 500 V and 0:25 W. Show that the voltage rating is the controlling limit for R > 1MΩ and that the power rating is the controlling limit when R
