Answer:
The electrical energy and time required for it to consume the same energy are
and 18 min.
Step-by-step explanation:
Given that,
Power = 90 W
Voltage V = 120 V
Current = 2.5
(a). We need to calculate the amount of energy
Using formula of energy

Where, p = power
t = time
Put the value into the formula



(b). We need to calculate the power
Using formula of power

Where, I = current
V = voltage
Put the value into the formula


We need to calculate the time
Using formula of time

Put the value into the formula



Hence, The electrical energy and time required for it to consume the same energy are
and 18 min.
