What is resistance capacitance inductance and their units?
Answers
Resistance
→ Resistance is the ability of a component to supply necessary potential difference to the components of a circuit by regulating the current flow in a circuit. The components having this ability are called resistors.
→ Resistance is indicated by the letter R.
→ The unit of resistance is Ohm, named after the German physicist Georg Simon Ohm.
→ The unit Ohm is indicated by the Greek letter Omega (uppercase) (Ω).
Capacitance
→ Capacitance is the ability of a component to store electric charge in a circuit and release it when necessary. The components dealing with this process are called capacitors.
→ Capacitance is indicated by the letter C.
→ The unit of capacitance is Farad, named after the English physicist Michael Faraday.
→ Farad is indicated by the letter F.
→ Practical units of capacitance are microfarad (μF = 10^-6 F), nanofarad (nF = 10^-9 F), picofarad (10^-12 F), etc.
Inductance
→ Inductance is the ability of a component to resist variations of electric current in a circuit without energy loss. The components having this ability are called inductors. Usually coils of conducting wires are used as inductors.
→ The advantage of using an inductor over a resistor is that energy can be saved without any loss.
→ Inductance is usually indicated by the letter L.
→ The unit of inductance is Henry, named after the American scientist Joseph Henry.
→ The unit Henry is indicated by the letter H.
→ Milli Henry (mH = 10^-3 H) is the practical unit of inductance.
