Question

State two factors on which the electrical energy consumed by an electrical appliance depends.

Answer 1

Hint: As per the question, the factors on which the electrical energy consumed by an electrical appliance depends means, what is the cause of the consumption of electrical energy. So, power and current helps electrical energy consumption.

Complete answer:
Electrical energy consumed by an electrical appliance depends on:
(i) Power rating of the appliance.
(ii) Current
The electrical energy consumed per second by an electric appliance when connected across the voltage of the mains is known as its power rating. Most appliances have a power rating that can be found on the item or in the handbook. We recommend that you seek up the rated power of each device to be powered for a final estimation of your watt-hour usage.
Electric and electronic devices use electricity to produce the intended result (i.e., light, heat, motion, etc.). During operation, some of the energy is wasted in unwanted output, such as waste heat, depending on the electrical efficiency.
Or, in other words, there are two factors depending on consuming electric energy such as time and power of appliances. This is measured by $E = PT$ and an appliance may run for a long time and consume more electric energy.

Note:
The power rating of equipment is the maximum power input allowed to pass through certain equipment in electrical and mechanical engineering. A power rating can include both average and maximum power, which can differ based on the type of equipment and its intended use.
