1 An ideal 5.2 V voltage source is connected to two resistors in parallel series. One is 1.2$k\Omega$, and the other is 2.8 $k\Omega$. What is the current through the larger resistor?

2 A 7.7 ohm resistor is connected in series to a pair of 5.8 ohm resistors that are in parallel. What is the net resistance?

3 Two 8 ohm resistors are connected in parallel. This combination is then connected in series to a 6.6 ohm resistor. What is the net resistance?

4 An ideal 7.9 volt battery is connected to a 0.09 ohm resistor. To measure the current an ammeter with a resistance of 20$m\Omega$ is used. What current does the ammeter actually read?

5 A battery has an emf of 5.3 volts, and an internal resistance of 326 $k\Omega$. It is connected to a 3 $M\Omega$ resistor. What power is developed in the 3 $M\Omega$ resistor?
