The Net Flow of Charge. In the field of physics, the Coulomb (often denoted by the symbol ‘C’) can be defined as the unit of electric charge. As per the International System of Units (often abbreviated to SI), one Coulomb of charge is equal to the charge transported by an electric current of constant magnitude in one second of time.

Q. Which of the following units could be used to measure electric charge? (a) ampere (b) joule (c) volt (d) coulomb. Q. (a) State the relation between potential difference, work done and charge moved. (b) Calculate the work done in moving a charge of 4 coulombs from a point at 220 volts to another point at 230 volts. Q.
Coulomb’s Law of Electrostatics. We begin with the magnitude of the electrostatic force between two point charges q and Q. It is convenient to label one of these charges, q, as a test charge, and call Q a source charge. As we develop the theory, more source charges will be added.
Ampere meter, commonly known as Ammeter is an electrical instrument used to measure electrical current in Amperes. The electrical current on the load is measured with the help of an Ampere meter by connecting it in series to the load. It has zero resistance, and so the measured circuit remains unaffected.
The suffix micro is equivalent to 10 -6. 1 microcoulomb is equivalent to 10 -6. Hence, 1 m i c r o c o u l o m b μC = 10 - 6 C. Suggest Corrections.
Mathematically, it can be written as I = Q t, o r Q = I t, where Q is the charge, I is the current and t is the time. One ampere is the current which flows when one coulomb of charge passes in one second. Q = I t, o r 1 C o u l o m b = 1 a m p e r e x 1 s e c.
Epsilon Naught is synonymous to the permittivity of free space or absolute permittivity or electric constant, represented by the Greek alphabet ε0. The Epsilon Naught value is constant at any part of the universe. It is often miss-used as the value of Epsilon not. Permittivity is the measure of the opposition offered against the formation of ...

SI Unit of Capacitance. The SI unit of electrical capacitance is Farad which is represented by the symbol F. The unit is mainly named after English physicist Michael Faraday. Farad is also defined as the ability of an object or body to store an electrical charge. It is represented in terms of SI base units like s 4 ⋅A 2 ⋅m -2 ⋅kg -1.
