Energy is defined as the capacity to do work.

It is given in the question that

A 1600 watts electric oven is used for 9 hours

Power * Time

power = 1600 watts

Time = 9 hours

Total energy consumed = 1600 watts * 9 hours
= 14,400 watts hour

energy is measured in Kilowatts hour

= 14,440 watts hour

14,440/1000 kwh

= 14.4 kwh

It is given that the cost per unit of energy is $3.00 per kwh

Therefore , the cost of using 14,400 watts hour would be 14.4 * 3

= $43.2

The function of Voltmeter and Ammeter is to measure Voltage and Current respectively.
