Step 1
Given that the voltage drop across the resistor is 28V, we can use Ohm's Law to find the current flowing through the circuit: I = V/R where I is the current, V is the voltage drop across the resistor, and R is the resistance. Substitute the values: I = 28V / R Show more…

A circuit is wired as shown. Initially, the capacitor is uncharged and switches S1 and S2 are open. What is the voltage Vc across the capacitor immediately after switch S1 is closed? Vc = 0 Vc = V Vc = 2/3 V What is the voltage across the capacitor after switch S1 has been closed for a very long time? Vc = 2/3 V Vc = 0 Vc = V After being closed for a long time, switch S1 is opened and switch S2 is closed. What is the current IR through the right resistor immediately after switch S2 is closed? IR = 0 IR = V/3R IR = V/R IR = V/2R Now suppose both switches are closed. What is the voltage across the capacitor after a very long time? Vc = V Vc = 2/3 V Vc = 0
