Proportional to dqdt c.

Instantaneous power in inductor is proportional to the. Proportional to q b. B v when ac goes through a complete ve to ve is called a cycle. And power in a circuit is given as.

Both a and c. The instantaneous current through the inductor must have the sine wave shape shown by the red curve in figure 2 in order to induce the sinewave voltage that appears across the inductor. Energy in an inductor.

When power flows into an inductor energy is stored in its magnetic field. What this means is that reactance in ohms for any inductor is directly proportional to the frequency of the alternating current. An inductor with inductance l and a capacitor with capacitance c are connected as shown in 3015.

The current flowing through the inductor generates the magnetic field where the energy is actually stored. At any instant the potential difference between the capacitor plates is a. Hence instantaneous power in an inductor is proportional to the product of instantaneous current and rate of change of current through it.

A when ac completes the ve half is called a cycle. Like the ideal capacitor the ideal inductor does not dissipate energy and the energy stored in it can be retrieved at a later time. The inductor takes power from the circuit when storing energy and delivers power to the circuit when returning previously stored energy.

Proportional to d2qdt2 d. C when an alternating quantity completes the ve cycle is called a cycle. The instantaneous voltage across the inductor is expressed as the product of inductance and rate of change of current through it.

Instantaneous power in inductor is proportional to a product of instantaneous current and rate of change of current b square of instantaneous current c square of rate of change of current d temperature of the inductor. The value of the capacitor charge q oscillates between positive and negative values. In a pure inductive circuit instantaneous power may be positive or negative because instantaneous power is the product of the instantaneous voltage and the instantaneous current pie the power equals zero whenever the instantaneous current or voltage is zero.

An ideal inductor has no resistance only inductance so r 0 w and therefore no power is dissipated within the coil so we can say that an ideal inductor has zero power loss. In a pure inductor the energy is stored without loss and is returned to the rest of the circuit when the current through the inductor is ramped down and its associated magnetic field collapses. Since inductors drop voltage in proportion to the rate of current change they will drop more voltage for faster changing currents and less voltage for slower changing currents.

Power is expressed as the product of current and voltage.
