energy dissipated in charging a capacitorSome energy is s ent by the source in charging a capacitor. A part of it is dissipated in the circuit and the rema ning energy is stored up in the capacitor. In this experim nt we shall try to measure these energies. With fixed values of C and R m asure the current I as a function of time. The ener
Consider a circuit having a capacitance C and a resistance R which are joined in series with a battery of emf ε through a Morse key K, as shown in the figure. When the key is pressed, the capacitor begins to store charge. If at any time during charging, I is the current through the circuit and Q is the charge on the capacitor, then
tudy the adiabatic charging of a capacitorIs there no way of eliminating or reducing the dissipation of energy 1 2 2CV in charging of a ca acitor? The answer is yes, there is a way. Instead of charg-ing a capacitor to the maximum voltage V0 in a single step if you charge it to this voltage in small step
be independent of the charging resistance.In charging or discharging a capacitor through a resistor an energy equal to 1 2CV 2 is dissipated in the circuit and is in ependent of the resistance in the circuit. Can you devise an experiment to measure it calorimetrically? Try to work out the values of R and C that y
This charge displacement causes an electric field E to be built between the plates, the value of which is given by E = U/d, U being the instantaneous voltage across the capacitor. This voltage reaches its maximum U = Ub after a certain time period.
