dleccord said:if the inductor is at dc steady state, the inductor would act like a short.
in this case, why would the voltage across the inductor be zero?
thanks in advance.
In a DC circuit, the voltage across an inductor is 0 at steady state because of the principle of inductance. An inductor resists changes in current flow, so when a DC current is applied, the inductor initially resists the change and causes a buildup of magnetic energy. Once the current reaches a steady state, the magnetic field around the inductor remains constant and the inductor no longer resists the current, resulting in a voltage of 0.
An inductor is an electronic component that stores energy in the form of a magnetic field. In a DC circuit, the inductor acts as a temporary reservoir for electrical energy, resisting changes in the current flow and smoothing out fluctuations in the circuit.
Yes, there are scenarios in which the voltage across an inductor can be non-zero in a DC circuit. For example, if the current in the circuit is changing, the inductor will resist the change and create a non-zero voltage. Additionally, in a circuit with multiple inductors, the voltage across one inductor may be non-zero while the others have a voltage of 0.
The voltage across an inductor in a DC circuit is different from that of a resistor. In a resistor, the voltage and current are in phase, meaning they both peak and drop at the same time. In an inductor, the voltage and current are out of phase, meaning the voltage peaks after the current peaks. Additionally, a resistor dissipates energy in the form of heat, while an inductor stores energy in its magnetic field.
Yes, the voltage across an inductor can change in a DC circuit. As mentioned before, if the current in the circuit is changing, the inductor will resist the change and create a voltage. Additionally, if the properties of the inductor, such as its inductance or resistance, are altered, the voltage across the inductor will also change.
