Compare Resistance in Series And Parallel : Electric Circuits

In electric circuits, two quantities are of interest, primarily: Current & Voltage

connection between two electric elements is said to be

• in series if the current is the same in the two
• in parallel if the voltage is the same in the two

SERIES CIRCUITS

• There is just one current pathway ,
• All elements have identical present by them.
• The sum of potential drops throughout every part is the same as the emf of the supply. This statement is named kirchoff’s voltage law.
• In series circuit it follows that if there’s a break in any a part of the circuit, no current flows.For this reason fuses, circuit breakers and safety switches are positioned in series with the home equipment they’re designed to guard.
• Ammeters are positioned in series with the part whose current you are trying to measure.

The properties of a series circuits are :

PARALLEL CIRCUIT

• There’s multiple current pathway,
• All elements have the identical potential distinction throughout them.
• The sum of current flowing into any ponit in circuit equals the sum of currents flowing out of that point.This statement is called kirchoff’s current law.
• In parallel circuit, every component acts as if it have been the one one present. A break in a single circuit would not have an effect on the others. Not like a series circuit, it is not ‘ one out all out’ !.
• Voltmeter are positioned in parallel with the component whose voltage you are trying to measure.

The properties of a parallel circuit are :

• The whole resistance is lower than anybody resistance.
• Voltage stays same through the circuit.
