An ideal 12V DC power supply is connected to two resistors, R1=6Ω and R2=3Ω, that are wired in parallel. An ideal ammeter is inserted in the single wire that leads from the positive terminal of the power supply to the junction of the two resistors. An ideal voltmeter is connected directly across resistor R2.
(a) Determine the equivalent resistance of the parallel network.
(b) Calculate the current through each resistor.
(c) State the reading of the ammeter.
(d) State the reading of the voltmeter.
