YOUR ANSWER: 25 watts.
Right. P is still equal to E x I.
What is the power consumption in the circuit?
YOUR ANSWER: P = E x I.
Well, at least you remembered the basic power formula.
But you were asked, which formula you would use to solve for power, if voltage and
We just gave you the formula on the preceding page: P = E2
Here is an explanation as to how we arrive at this formula. P = E x I in our basic power
formula. I = E in Ohm's law. We car, substitute E for "I" in the basic power
law; thus, P = E x F or P =E2.
Now, go back to frame 9A and select the correct answer.
