Answer:
A
Explanation:
Because of the convectional currents
Answer:
Explanation:
I = V/R = 120 V/ 50 Ω = 2.4 A
P = VI = 120(2.4) = 288 W = 288 J/s
288 J/s (15 min(60s / min)) = 259,200 J
or the electric company would charge for
288 W / (1000 W/kW)•(15/60) hr = 0.072 kW•hr
At $0.20 / kW•hr, that would be under 1½ cents
