An RC circuit, with R = 650Ω and C = 500μF, takes 0.5s for the voltage drop across the capacitor to decay to 5 V . What was the voltage drop across the capacitor at the start of the 0.5 s period?

In the circuit shown the capacitor starts discharged. The switch S is closed to theupper position at t = 0.(a) What is the voltage in the capacitor at t = 2 seconds?(b) How much time does it take the capacitor to reach 99% of its maximum voltage.

In an RC series circuit, ℰℰ = 12.0 V, R = 1.07 MΩ, and C = 2.16 µF. (a) Calculate the time constant. (b) Find the maximum charge that will appear on the capacitor during charging. (c) How long does it take for the charge to build up to 20.5 µC?

The capacitor in the circuit shown is fully charged by a 24 V battery. The switch is closed at t = 0. At sometime after the switch is closed, the voltage across the capacitor is measured to be 10 V. What is the current in the circuit at this time, in Ampere? C = 3.0 µF, and R = 2.0 02. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. Cil

A series RC circuit with C = 48 mF and R = 50 Ω is driven by a 24 V source. With the capacitor initially uncharged, an open switch in the circuit is closed to complete the circuit. What is the voltage across the capacitor immediately after the switch is closed? What is the voltage across the resistor immediately after the switch is closed? What is the current in the resistor immediately after the switch is closed? What is the voltage across the capacitor after the switch has been closed for 1 s? What is the voltage across the resistor after the switch has been closed for 1 s? What is the current in the resistor after the switch has been closed for 1 s?
