A current is passing through a resistor for a certain
time. The current is doubled and the resistance
halved while the time remains the same. What
happens to the heating effect?

Explanation:
The current is directly proportional to the voltage and inversely proportional to the resistance.So doubling or tripling the resistance will cause the current to be one-half or one-third the original value. a. The new current will be 0.5.
Hope its help..
