A 24 V ideal power supply is connected to a resistive network that contains three resistors: R1=4Ω is in series with a branch consisting of R2=6Ω in parallel with R3=12Ω.
(1) Calculate the equivalent resistance of the entire network.
(2) Determine the current that leaves the power supply.
(3) Find the potential difference across each of the three resistors.
(4) Compute the power dissipated in each resistor.
(5) Verify quantitatively that energy is conserved by comparing the total power dissipated in the resistors with the power supplied by the source.
