-The amount of charge that must be moved from one side of the capacitor to the other to establish a voltage, V, for a capacitor with capacitance, C, is given by . Calculate the amount of charge that will be moved from one side of the capacitor to the other if we hook a 10 V battery up to the 25000 μF capacitor. Show your work and pay attention to units.

Q=

2. The capacitor is charged to 10 V and then connected to a 100 Ω resistor in the circuit shown to the right. If the voltage across the capacitor is 10 V, voltage will be across the resistor right after the circuit is connected?

VR =

The loop rule for circuits may be useful here. The total change in voltage (or the total potential difference) must be zero whenever we go around a closed loop.

3. Using the voltage across the resistor, calculate the amount of current that must be flowing through the resistor (and in the rest of this single loop circuit) immediately after we connect the circuit as shown. Remember that the voltage across the resistor is given by ?VR=IR. Show your work.

I =

Which way is current flowing
