AC Circuits and Voltage

The AC voltage is produced due to the change in magnetic flux at an oblique angle.

Direct current (DC) flows only in one direction and periodically reverses its direction.

Capacitive reactance is a fixed impedance value of a capacitor.

An open circuit is a type of electric circuit where charges or electric current flow continuously.

Faraday's Law of Induction specifies how electric currents can be induced in a stationary coil.

The electric current in an AC circuit flows only in one direction.

The AC voltage is produced due to the change in magnetic flux at a right angle.

Capacitive reactance is a constant resistance inside a capacitor.

An AC circuit is a type of open circuit.

The current change in an AC circuit is proportional to the square of the rate of change in magnetic flux.

Electric Circuit

An electric circuit is a closed path or loop through which charges or electric current flow continuously.
It is a closed conducting path for electrons, also known as an electrical circuit or electrical network.
Circuits can be found in various types such as open, closed, series, parallel, etc.

AC Circuit

An AC circuit is a type of electric circuit.

AC Voltage

AC voltage is made possible thanks to Faraday’s Law of Induction.
The law specifies how electric currents can be induced in a moving coil as it cuts through magnetic flux at the right angle.
The current change is proportional to the rate of change in magnetic flux.

AC Current

Alternating current (AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time.
AC is in contrast to direct current (DC), which flows only in one direction.

AC Reactance

Capacitive Reactance is the complex impedance value of a capacitor.
It limits the flow of electric current through it.
Capacitive reactance can be thought of as a variable resistance inside a capacitor being controlled by the applied frequency.
