Chapter 4 Principles of galvanic Circuits, Conventional Flow, 9th ed. Floyd © 2010 Pearson Higher Education, upper berth accuse River, NJ 07458. altogether Rights Reserved Chapter 4 Energy sum-up 1n Energy, W, is the ability to do work and is measured in joules. one and only(a) joule is the work d matchless when a forces of one newton is applied through a trump of one meter. The symbol for energy, W, represents work, but should not be intricate with the building block of measurement for force-out, 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 minutes? 1200 W = 1.2 kW 2 0 min = 1/3 h 1.2 kW X 1/3 h =0.4 kWh Principles of Electric Circuits, Conventional Flow, 9th ed.

All Rights Reserved Chapter 4 business leader Summary Power is the measure energy is used (actually reborn to heat or another form). Power is measured in watts (or kilowatts). Notice that rate always involves time. One watt = one joule/ present moment Three equations for power in circuits that argon collectively know 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 determine into P =I 2R. P = I 2R = (0.135 A) 2 ( 27 ? ) = 0.49 W Principles of Electri c Circuits, Conventional Flow, 9th ed.
