CWEA E1 Study Set* Q&A

If transformer primary=120v and secondary 12v=20 amps, what are the amps on the primary? 2 amps. Formula: I =Amps/Volume of current E = Volts/Force moving the current P = Watts, Electrical power produced I x E=P 12 x 20=240watts In a transformer watts stay the same so now: P/E=I 240/120v=2 amps If 17.32v are applied across a resistance of 50 ohms, how much power is expended in the resistor? 6.0 watts. Formula: V squared/R = P 17.32 squared(299.98)/50=5.99 Confined Space A spa...
