Question

4.1.2 quiz: electricity
question 6 of 10
what is the power (p) of an electric circuit with a current (i) of 6.5 a and a voltage (v) of 120 v? the formula for power is ( p = iv ).
a. 27 w
b. 780 ω
c. 27 ω
d. 780 w

Explanation:

Step1: Substitute the given values into the formula

Given \(I = 6.5\space A\) and \(V=120\space V\), substitute into \(P = IV\).
\(P=(6.5)(120)\)

Step2: Calculate the product

\(6.5\times120=(6 + 0.5)\times120=6\times120+0.5\times120=720 + 60=780\)

Answer:

D. \(780\space W\)
