discussion problem 4: Why does the voltage across the capacitor (and neon tube) decrease as the capacitor is discharging? math-physics problem 1: Show that the flow of charge on the capacitor is dq Vbatt – q/C %3D dt R where Vhatt is the voltage across the battery, R is the resistor, and C is the capcitence. To do this you will need to apply Kirchoff's loop law. Also, the method of the RC circuit in the book is very similar (check the book).

Consider the following circuit diagram, assuming the voltage is V = and all the capacitors have C = 2µF. 10v, C, C3 C5 a) By finding the equivalent capacitance, and then working backwards, find the voltage drop across each capacitor, and the charge stored on each ca- pacitor. b) What is the energy stored in each capacitor? c) Now replace each capacitor with R= 20 resistors. By finding the equiv- alent resistance and working backwards, find the voltage drop across each resistor and the current through each resistor. d) What is the power dissipated by each resistor? What is the power deliv- ered by the voltage source?

True or False. As the charge in the capacitor increases, the voltage AV_R across the resistor decreases. Please explain why this is true.

d)  Find the power delivered to the resistor e) Find the rate at which the energy stored in the capacitor is increasing

A fully charged capacitor with capacitance of C= 80 uF is being discharged.

A capacitor is charged from the battery with EMF E = 10 V through the resistor R. Whatenergy is released on the resistor in the form of heat if the capacitance is C = 5 mkF?

A 12.0-V battery is attached to a 2.00-mF capacitor and a 100-Ω Once the capacitor is fully charged, what is the energy stored in it? What is the energy dissipated as heat by the resistor as the capacitor is charging?

A 1 uF capacitor is connected in series with a 2 uF capacitor and an open switch. Initially, the voltage across the open switch is 12 V and the voltages across the two capacitors are equal. a) b) Draw this circuit, marking on your diagram values of voltage V, charge Q and stored energy E in appropriate places. The switch is now closed. A current will flow, and excess energy will be dissipated in heat in the wires. Make a second diagram showing the final values of the voltages V, charges Q and stored energies, and state the amount of energy dissipated. E
