Ohm's Law & the Power Wheel: Volts, Amps, Ohms & Watts
This lesson is part of the course
In this lesson
You turn the nameplate watts of six plug-in loads into amps and ohms, work out current and power of four 240 V heating elements and check whether the whole circuit stays under an illustrative 80 % continuous-load limit.
