Hey, i got a circuit question, and I'm not sure if i did it right, and was wondering if anyone could show me how to do it
A 750W microwave oven is plugged into an outlet and turned on. All three lights are on. What is the maximum power rating of a kettle that could be operated in the other outlet without burning out the fuse.
a) 1.80 x 10^3W
b) 7.50 x 10^2W
c) 1.05 x 10^3W
d) 9.50 x 10^2W
What i did is, for each awnser i took the power reading and divided it by the total voltage, since P = IV P/V = I, i found out that the 1800W one produced a current of 15A and that was my awnser, but my other friends got 1500Wats as the
