I will be posting the solution to the quiz this weekend so that you may review it before the exam.

Consider the circuit above. The internal resistance of the battery is 2 ohm.

- What is the effective resistance of the circuit?

*(Hint: it is***not**27 ohm, nor is it 1.5 ohm!) - What is the current through the battery?
- What is the voltage across the 10 ohm resistor?
- What is the current through the 15 ohm resistor?
- What is the power dissipated by the 15 ohm resistor? by the 10 ohm resistor?
- What is the power supplied by the battery?
