Once the capacitor has fully charged the current in the circuit will be zero, so the voltage drop across the resistor is zero and hence the voltage across the capacitor is equal to the cell voltage. The inductor absorb power is

Thus, the heat energy appearing in the resistor is equal to the energy stored in the inductor. V = 0 volts and q = 0 C. When a capacitor charges in a simple series RC (resistor-capacitor) circuit, the energy stored in the capacitor increases as it charges and the resistor dissipates energy as the capacitor charging current passes through it. This energy goes into heat, much like the way a ball of putty that falls off a cliff converts its potential energy to heat when it hits the ground. Again, there is energy associated with the magnetic field. The energy density in a magnetic field is Energy density in a magnetic field = B 2 /(2μ 0). Energy has been transferred from the chemical energy store of the battery into the internal energy store of the wire. This takes energy from elctric current flowing to align themselves and is stored as magnetic enrgy. This energy is actually stored in the magnetic field generated around the inductor. We refer to this conversion of potential energy into heat as dissipation. The rate at which energy is stored in inductor, Capacitors in Series. Having said this, the current falls exponentially with time so in principle the current takes an infinite time to fall to zero, and the voltage across the capacitor takes … At the very beginning, capacitor does not have any charge or potential. Capacitors in Series and Parallel. In series RL circuit, some energy is dissipated by the resistor and some energy is alternately stored and returned by the inductor- The instantaneous power deliver by voltage source V is P = VI (watts). The circuit equations are thus (939) where is the e.m.f. So the instantaneous power from the source is p (t) = V i (t). The resistor while dissipate it in heat form. P = IVcosɸ In the first and third quarter of the period , the energy is stored in the magnetic field of the inductor, but in the 2nd and 4th quarter of the period , the energy is released from the inductor to the rest of the circuit. Energy dissipation in resistors. Circuit. Power dissipated by the resistor in the form of heat, P = I 2 R (watts).
In an inductor when electric current is flown the magnetic field is formed in the coil due to Ampere'law. Consider, again, our circuit with two coils wound on top of one another.


In series, capacitors will each have the same amount of charge stored on them because the charge from the first one travels to the second one, and so on. Power in an A.C. It stores electric energy in the form of the magnetic field during the charging phase and releases the same energy to the circuit in the decay phase.

Energy stored in a capacitor is electrical potential energy, and it is thus related to the charge Qand voltage Von the capacitor. This energy goes into heat, much like the way a ball of putty that falls off a cliff converts its potential energy to heat when it hits the ground. Resistor and capacitor perform different functions in terms of the power in the circuit: resistor – dissipates energy, and capacitor – stores energy. The rate at which energy is stored in inductor, As a charge q moves through a resistor, it loses a potential energy qV where V is the potential drop across the resistor. In series RL circuit, some energy is dissipated by the resistor and some energy is alternately stored and returned by the inductor-The instantaneous power deliver by voltage source V is P = VI (watts).
