The correct term for the flow of electricity is current. Current is the number of electrons flowing per second in a circuit. The unit of electrical current flow is called the ampere. When 6.28 billion electrons pass a given point, this is called 1 coulomb. 1 coulomb per second is equal to 1 amp of current. Current flow is measured with an ammeter.

FranJust as the flow of water in a river constitutes a current of water, flow of charge, i.e. charges in motion constitue an electric current. - The charged particles whose flow in a definite direction constitutes the electric current are called current carriers.e.g. electrons in conductors,ions in electrolytes,electrons and holes in semiconductors. The essential requirement for maintaining a steady current is a source of e.m.f. e.m.f. is associated with an arrangement or mechanism which can supply energy or does work to move the electric charge from lower potential energy to higher potential energy.

What does the energy carried by an electric current depend on?
The energy carried by an electric current depends on the voltage of the source and the amount of charge flowing through the circuit. It is defined as the product of voltage, current, and time.
What is a device that measures the strength of an electric current?
An ammeter is a device that measures the strength of an electric current. It is usually connected in series with the circuit where the current is to be measured and provides a reading in units of amperes.
Can a displacement current be measured with an ammeter expain?
Displacement current can not be measured by ammeter because it is the current which produce between the plate (space)due to change of electric flux and it is directly proportional to the rate of change of electric flux.
Can a electric current affect a compass?
Yes, an electric current can affect a compass. When an electric current flows through a wire, it creates a magnetic field around the wire. This magnetic field can interfere with the Earth's magnetic field that the compass relies on for navigation.
How electric current causes magnetic field around conductor?
When an electric current flows through a conductor, it creates a magnetic field around the conductor. This is due to the interaction between the moving charges (the electrons in the current) and the magnetic fields they produce. The magnetic field strength is directly proportional to the current flowing through the conductor.
