Answer : The power produced by light bulb is, 5.4 watts
Solution : Given,
Voltage = 120 V
Current = 0.045 A
Formula used :

where,
P = power produced by light bulb
V = voltage
I = current
Now put all the given values in the above formula, we get the power produced by the light bulb.

Therefore, the power produced by light bulb is, 5.4 watts
