1.        Calculate the terminal voltage for a battery with an internal resistance of and an emf of 6.00 V when the battery is connected in series with a 71.0 Ω resistor.

2.        Calculate the terminal voltage for a battery with an internal resistance of and an emf of 6.00 V when the battery is connected in series with a 710 Ω resistor.

3.        What is the internal resistance of a 12.0-V car battery whose terminal voltage drops to 8.8 V when the starter motor
draws 95 A?

4.        What is the resistance of the starter?

5.        Consider the combination of resistors shown. Find the equivalent resistance between point a and b.

6.        If a voltage of 35.0 V is applied between points a and b, find the current in each resistor.

  1. We can consider R1 to be the resistance of wires leading to R2 and R3. Find the total resistance.

  1. What is the voltage drop in R1?

  1.  Find the current through R2.

  1.  What power is dissipated by R2?
