Question

How much current does a 310 W device draw when given a voltage of 120 V?

A. 4.0 × 10^-2 A

B. 2.6 × 10^0 A

C. 4.2 × 10^2 A

D. 3.6 × 10^4 A

Answer 1

here we have to apply this formula:
\[\Large I = \frac{W}{{\Delta V}} = \frac{{310}}{{120}}\]

Answer 2

2.58? so our solution is choice B?

Answer 3

yes! that's right!

Answer 4

yay! thank you!:D
