Answer:
40 Joules
Explanation:
t = time interval of operation = 2 sec
V = Battery voltage applied across the ends of resistor = 10 volts
i = current flowing through the resistor in the given time interval = 2 A
W = work done by resistor
Work done by the resistor can be given as
W = V i t
Inserting the above values
W = (10) (2) (2)
W = 40 Joules
