Two resistors, 80.0 and 66.0 , are connected in parallel. The current through the second resistor is 2.40 A.
What is the current in the first resistor?
What is the total power supplied to the two resistors?
I got the answer for the first question but i cant get the answer for the second.
The two resistors have the same voltage across them,
I2*R2 = 66*2.4 = 158.4 Volts = I1*R1
I1 = 158.4/80 = 1.98 A
Total current = 1.98 + 2.40 = 4.38 A
Total power = V*I = 158.4*4.38 = 694 W
Second resistor power = I2^2*R2 = 380 W
First resistor power = I1^2*R1 = 314 W
