Current is the generic term to describe the flow of something. This could be electrons in a wire (electric current) - or the movement of water in a river (a water current).
It can also be used to denote "now" as in "the current time is 12.00" or "current affairs"
Electric current is defined as the movement of electrical charges.
When a capacitor is discharging, current is flowing out of the capacitor to other elements in the circuit, similar to a battery. Current flowing out of an element, by convention, is defined as negative current, while current flowing into an element, such as a resistor, is defined as positive current. Thus a discharging capacitor will always have a negative current.
Movement of electrical charges
The telephone does that!
A: An ideal current source can be defined as a short with immense current capabilities A zener has no such capabilities
'Real', or 'true', power is defined as the rate at which work is done by the in-phase component of an alternating current.
can't as there is only one: they are in opposite directions. conventional current flow was defined arbitrarily before the discovery of electrons to permit mathematical analysis of circuits. electron current flow was defined after the discovery of electrons.
Resistance is the measure of how much a material or component opposes the flow of electric current. In electrical terms, resistance is defined as the ratio of voltage to current in a circuit, measured in ohms.
A microphone is the device that changes sounds into electric current.

The unit of current intensity is the ampere (A), which is defined as the flow of one coulomb of charge per second in a circuit.
