Consider the circuit below. The emf of the ideal battery is 4.5 V, the capacitor has capacitance of 0.150 μ1F, and the resistances are R1 = 120 Ω, R2 = 360 Ω, and R3 = 250 Ω. The switch is initially open and the capacitor is fully charged.
What is the current through R1?R2?R3?
How much charge is stored on the capacitor?
What is the potential at the junction where R1, R2, and C meet?
What is the current through R1 right after the switch is closed?R2?R3?
At what rate is the charge on the capacitor changing right after the switch is closed? Enter a positive number if the charge on the capacitor is increasing or a negative number if it is decreasing.
