1. what is AC Circuit?
Ac - Alternative Current . The Circuit Which Uses Alternative Current As Power Or Source
Its Continuously Changes Its Position Both Voltages And Current.
A.c Have One Upper Side waves And Down Side Wave
But Both The Waves Position Are Alternative Position One Is Positive Wave Other Is Negative Wave That Why Its Called Alternative Wave Or Signal

The Waves Position Are Alternative Position |
2. Why There Is Series And Parallel ? Why Its Important ?
Generally current and voltage flow graph or relationship is different.
In parallel circuit Current Split up i.e current will not be same in all component but voltage is same
In series just opposite voltage will not be same and current is same

AS
YOU CAN SEE THIS A SERIES CIRCUIT I HAVE CONNECTED AS 10V BATTERY 3
RESISTOR OR LOAD , VOLTAGE IS NOT SAME IN EACH LOAD. CURRENT ,
ohms law, I = V / R
10 v / 4700
= 0.0021276 or 2.127 mA (milli ampere)
throughout circuit same resistance but different voltage and same current
SERIES AND PARALLEL A.C. CIRCUITS :
In a series circuit, the current being same through each of the impedance, the voltage phasor are related to the current by the respective drop across each impedance vectorially added together.
