What Is The Charge On The Capacitor Immediately After The Switch Is Closed

What is the current i through the resistors immediately after the switch is closed. A 500 v battery is used to charge the 1 mf capacitor for 2 seconds.

It is changed to position b at t0.

What is the charge on the capacitor immediately after the switch is closed. What is the charge q on the capacitor at t50us. What is the charge q on the capacitor at. Can i use the equation vor trc substituting t0 for immediately after the switch closes and use r2r3 as r.

Immediately after the switch is moved form position a to b after long period of time the voltage stored in the capacitor will be 9 v. It is changed to position b at t0s. This is the current that starts to charge the capacitor.

As the voltage on the capacitor builds the current through the 600 ohm resistor will grow accordingly when the capacitor is fully charged no more current will flow into the capacitor branch from the junction. 3 determine the current in each resistor and the charge on the capacitor immediately after the switch has been re opened. For all the other question use this expression to calculate voltage across the capacitor and then use that voltage to calculate charge and current.

It is changed to position b at t 0 s. An rc circuit is connected across a dc voltage source through an open circuit and a switch. Immediately after charge on capacitor is same as immediately before after a long time current through capacitor 0 after xx seconds exponentially more difficult.

Now when the switch is opened the capacitor starts to discharge. If capacitor is discharging potential difference is zero and no current flows. If the capacitor is charging when fully charged no current flows and capppacitor acts as an o pen circuit.

After the switch has been closed for a long time it is re opened. Solve by applying kirchhoffs rules to circuit. The switch in the figure intro 1 figure has been in position a for a long time.

Capacitors in rc circuits. The switch in the figure has been in position a for a long time. What is the charge q on the capacitor immediately after the switch is closed.

So when the capacitor is charged the only current flowing is through r2. 4 determine the time constant of the capacitor discharge. As soon as the switch is closed the charge on the capacitor increases but the voltage across it decreases as a function of time.

Need to understand some key phrases. The switch in the figure has been in position a for a long time. What is the current i through the resistor immediately after the switch is closed.

What is the current i through the resistor at t50us.
