AC circuit involves alternating current that periodically reverses direction and changes its magnitude continuously with time in contrast to DC current which flows in only one direction. An AC circuit contains resistance, capacitance and inductance which cause the current and voltage to be out of phase with each other. AC current is important because it can be transformed into different voltages and controlled by various circuit components, allowing efficient long-distance power transmission. Common applications of AC circuits include power generation, transmission and distribution as well as powering electric motors and household appliances.

3. What is Ac current?
Ac is Alternating current electricity is the type of electricity commonly used
in homes and businesses throughout the world
AC electricity is created by an AC electric generator, which determines the
frequency
An AC waveform can be sinusoidal, square, or Triangular -shaped. Some
AC waveforms are irregular or complicated. ALTERNATING CURRENT

4. Alternating current flows first in one direction and then in the other
direction.

5. Shapes of AC Current

6. What is Electrical Circuit?
An electrical circuit is a complete conductive path through which electrons
flow from the source to the load and back to the source.
The direction and magnitude of the electrons flow however depend on the
kind of source.

8. Resistance in an AC circuit
 The resistors circuit the current and voltage are in phase with each
other, which means that the peak voltage is reached at the same instant as
peak current..

9. Capacitance in an AC circuit
The Capacitance they are 90° phase difference between the current and
voltage, with the current reaching its peak 90° (1/4 cycle) before the
voltage reaches its peak. Put another way, the current leads the voltage by
90° in a purely capacitive circuit.

10. Inductance in an AC circuit
The inductance they are 90° phase difference between the voltage and
the current in the inductor. This time, however, the current lags the voltage
by 90°, so it reaches its peak 1/4 cycle after the voltage peaks.

11. Why Ac current is important
he single greatest advantage of alternating current is that AC current can be
transformed into Dc current
It can be controlled by a wide range of components e.g.. resistors, capacitors
and inductors.
This allows high-voltage electrical power to be distributed with smaller wires
and lower amperage

12. What are the applications of alternating
current?
Alternating current is mainly used in the industry of the transportation and
production of electricity.
Alternating current use to get high voltages and current depending on our needs
of energy
AC is also the more popular current when it comes to powering electric motors,
a device that converts electric energy into mechanical energy.
Some household appliances that we use that rely on this are, but aren't limited
to: refrigerators,
