XC is inversely proportional to frequency and capacitance.
Electrostatic field is always in Capacitor, and Electromagnetic field is in inductor.
Energy is stored by an inductor in an electrostatic field.
Some factors that affect the inductance of a coil include:
1. The inductance is proportional to the square of the number of turns;
2. The inductance increases directly as the permeability of the core material increases;
3. The inductance increases directly as the cross-sectional area increases; and
4. The inductance decreases as its length increases.
Inductance is indirectly proportional to the square of the number of turns, the permeability, and the cross-sectional area of the core.
Inductance is the property of an inductor that produces an opposition to any change in current.
Faraday's law states that relative motion between a magnetic field and a coil induces a voltage across the coil.
An induced voltage is produced as a result of a dc voltage.
XL is directly proportional to frequency and inductance.
The permeability of a core material is an indication of the ability of the material to establish a magnetic field.
When a 15 V input pulse with a width equal to two time constants is applied to an RC integrator, the capacitor charges to
Following effects are associated with transmission lines
