Q

What is Mobility

A

Mobility is a measure of the ease with which a charge carrier can move through a material. It is typically measured in units of meters squared per volt-second (m^2/Vs) and affects the electrical conductivity of a material. Factors such as temperature, impurities and defects can also affect it.

Q

What is inductance?

A

Inductance is the ability of a circuit element to store energy in a magnetic field. Inductors are passive electronic components that store energy in a magnetic field when an electrical current flows through them. They are used in electronic circuits to filter out unwanted signals or to create specific time delays. The inductance is measured in henries (H) and the induced EMF is directly proportional to the rate of change of current and the inductance.

Q

What is capacitance?

A

Capacitance is the ability of a device or circuit element to store electrical energy in an electric field. Capacitors are passive electronic components that store electrical energy in an electric field. They are widely used in electronic circuits to filter out unwanted noise or to create specific time delays. The capacitance of a capacitor is a measure of the amount of electrical charge that can be stored per unit voltage applied and it is measured in farads (F) . The capacitance is determined by the physical properties of the materials used in the capacitor, as well as the size and shape of the capacitor.
