(a) What is the current in the first resistor?________A

Answer: 4.40 A

If two resistors with the same resistances are connected in parallel, the current through the first resistor is the same as the current through the second resistor.

(b) What is the total power supplied to the two resistors?________W

Answer: 2245.76 W

P1 = P2 = RI² = 58*4.4² = 1122.88 W
P = P1+P2 = 2*1122.88 = 2245.76 W
