Question

1) What is the total equivalent resistance?

2) What is the current in each resistor?

Item 13 Part A Three resistors with values of 5.0 , 8.0 , and 13 are connected in series in a circuit with a 7.0 V battery What is the total equivalent resistance? Express your answer using two significant figures Submit My Answers Give Up Part B What is the current in each resistor? Express your answer using two significant figures Submit My Answers Give Up Part C At what rate is energy delivered to the 13 resistor? Express your answer using two significant figures

Explanation / Answer

1)

5ohm, 8ohm and 13ohm are connected in series.

so equivalent resistance of circuit = 5 + 8 + 13 = 26 ohm

2)

current in each resistance = I = V/Req

I = 7/26 = 0.27 amp

3)

Energy delivered to the 13 resistor = I^2*R = (0.27)^2*13 = 0.947 watt
