You have three capacitors, of capacitance 1610pF, 7240pF and 0.0270 micro F. What is the maximum capacitance that you can form from these? What is the minimum capacitance that you can form from these?
A 2.61 micro F capacitor is charged to 1380 V and a 7.79 micro F is charged to 490 V. These capacitors are then disconnected from their batteries, and the positive plates are now connected to each other and the negative plates are connected to each other. What will be the charge on the 2.61 micro F capacitor and what will be th
A) Argue that the energy stored in the electric field of such a capacitor is Ufield=1/2CVo2, if Vo is the potential difference. (Hint: Argue that between the plates, the field strength is EVo/d, where dRo -RI is the distance between the conductors. Use the equation for the capacitance of a nested sell capacitor
1. A negative charge in an electric field moves from a point where the potential is zero to a point whre it is -100V. Discuss the energy change and the work done. 2. Imagine a hollow, spherical, positively charged conductor of radius R that is far away from any other bodies. Draw a graph of its potential V as a function of r
