anonymous one year ago 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

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

2.58? so our solution is choice B?

3. Michele_Laino

yes! that's right!
