Two electric resistors have equal values of resistance R. Each can be operated with a power of 320 watts (W) at 220 volts. If the two resistors are connected in series to a 110 volts electric supply, then the power generated in each resistor is
Text Solution
Verified by ExpertsThe correct answer is:
D
Given,
Power rating of resistor, 
watts
Voltage, 
volts
We know that power, 
Resistance of resistor, 
When the resistors are connected in series, then voltage across each resistor reduced to half.
Power in each resistor connected in series,
