Compound Direct Current Circuits Practice Test

An ideal $$12,\text{V}$$ battery is connected to a circuit consisting of a $$2,\Omega$$ resistor in series with a parallel combination of a $$3,\Omega$$ resistor and a $$6,\Omega$$ resistor.

Four identical resistors, each with resistance $$R$$, are available. They are first connected in series to an ideal battery, and the total current is $$I_S$$. They are then disconnected and reconnected in parallel to the same battery, and the total current is $$I_P$$.
