The symbol for energy, W, represents work, but should not be complicated with the unit of measurement of measurement for designer, the watt, W. 1m Principles of Electric Circuits, Conventional Flow, 9th ed.

There argon 3.6 x 106 J in a kWh. The kWh is convenient for electrical appliances. What is the energy used in operating a 1200 W heater for 20 proceedings? 1200 W = 1.2 kW 20 min = 1/3 h 1.2 kW X 1/3 h =0.4 kWh Principles of Electric Circuits, Conventional Flow, 9th ed.

Power is measured in watts (or kilowatts). Notice that rate always involves time.

One watt = one joule/ mho Three equations for power in circuits that argon collectively cognize as Watts fair play are: P = IV P = I 2R V2 P= R Principles of Electric Circuits, Conventional Flow, 9th ed.

Given that you know the resistance and current, utility(a) the value into P =I 2R. P = I 2R = (0.135 A) 2 ( 27 ? ) = 0.49 W Principles of Electric Circuits, Conventional Flow, 9th ed.
