### What is an Electric Circuit?

A circuit is a loop which connects the positive end of a power to  the negative end. The electrons are continuously  flowing  in a circuit. Current can flow through parallel or series circuit.

Electric circuits can be resistant or not – resistant. Resistors are  electronic components which have non- changing electrical resistance. The electrical resistance of a resistor is measured in Ohms.  Resistors are usually added to circuits  where they reduce current in the circuit.

#### The Ohm’s Law is also related to the resistance and its relationship with voltage and current-

V=IR is the equation .

having small resistance.  The total current is equal to the sum of the individual currents.

High Resistance  → Low Current

Low Resistance →  High Current

As we also prefer to go through that check-outstand  which comes first .  If there are two pathways we prefer to go through that one which consumes less time. So if  the current is more flowing through the resistors  that will result in an overall decrease in resistance.  So electric circuits can be like trying to get out through the check outline. If there is more load so it will create more resistance to the  flow of the current.

Electrical Circuits are like the  checkout line because they create a high resistance  to the  flow of current

The resistance can affect the  flow of current  also. It is different in a series and in a parallel circuit.  In a series circuit, the resistance increases as we add more resistors.

In a parallel circuit, it is different  from series one because the overall resistance decreases . In a parallel  circuit, there is more than one pathway,  that is more than one checkout line.  Current can go through any resistor because of the different pathways. More current will go through the resistor.
