series circuit:-
In a series circuit,
- There is only one current route,
- All components have the same current through them.
- The sum of potential drops in each component is equal to the EMF of the source. This statement is known as Kirchoff's voltage law.
In a series circuit, it follows that if there is a break in any part of the circuit, no current flows. This is why fuses, circuit breakers, and safety switches are kept in series with the equipment they are designed to protect.
The ammeter is placed in series with the component whose current you are trying to measure.
The properties of a series circuit are:
- Resistance is additive.
- The current remains the same throughout the circuit.
- The voltage is additive.
- Power is additive.
parallel circuit:-
In the parallel circuit,
- There is more than one current route,
- All components have the same capacity.
- The sum of the current flowing at any point is equal to the sum of the currents flowing from that point. This statement is known as Kirchoff's current rule.
In parallel circuits, each component acts as if it were the only one present. One break in one circuit does not affect the others. Unlike a series circuit, this series is not all out!
The voltmeter is placed parallel to the component whose voltage you are trying to measure.
The properties of a parallel circuit are:
- The total resistance is less than anyone resistance.
- The voltage through the circuit remains the same.
- The present is summative.
- Power is additive.
