Using Watt's law and substituting power can be calculated as_________

Question

Quizplus · Accepted Answer

Watt's law states that power (P) is equal to voltage (V) multiplied by current (I). This can be written as P=VI. However, Watt's law can also be rearranged to solve for voltage or current using Ohm's law (V=IR). Substituting this into the original equation gives P=I^2R. Watt's law can also be rearranged to solve for resistance (R=P/V^2), giving the third equation of P=V^2/R. Therefore, all three equations (A, B, and C) are valid forms of Watt's law.
