3. (8 points) Consider a conducting sphere with total electric charge +Q with radius Rị centered at p= 0 (spherical coordinates). The surface charge at r = R1 is spread uniformly on this spherical surface. There is also an outer conducting shell of radius r = R2, centered at r = 0 and with total electric charge - Q also spread uniformly on the surface. This arrangement of separated positive and negative charge forms a capacitor. We will assume that...

The total amount of charge that has entered a wire at time t is given by the expression Q=(74C)(1−e−t/(2.0s)), where t is in seconds and t≥0. Part B What is the maximum value of the current? Express your answer using two significant figures.
A large capacitor has a charge + q on one plate and -q on the other. At time t = 0, the capacitor is connected in series to two ammeters and a light bulb
A large capacitor has a charge + q on one plate and -q on the other. At time t = 0, the capacitor is connected in series to two ammeters and a light bulb. Immediately after the circuit is closed, the ammeter connected to the positive plate of the capacitor reads Ip and the ammeter connected to the negative plate of the capacitor reads IN. (Figure 1) Each ammeter reads positive if current flows through the circuit in a clockwise direction (from...
