Parallel Circuits
Parallel circuits are defined as a type of circuit in which various electrical components or resources are connected across one another in parallel. This circuit contains two or more paths for the flow of electric current. In this circuit the amount of voltage across each resource or components is constant or same. The amount of electric current through each component is variable.
Properties of Parallel Circuits
- The voltage or potential difference is same across each electrical components in the circuit.
- The total amount of current flowing through the circuit is sum total of all the individual electric current flowing through each components.
I = I1 + I2 + I3 + … + In
- The equivalent electrical resistance of the circuit is calculated in following way
R = 1/R1 + 1/R2 + … + 1/Rn
- The equivalent electrical resistance is the minimum of all the individual resistance.
R < R1, R < R2, …, R < Rn
Example: If 2 resistors of 3ohm and 4ohm are connected in parallel. What is the resistance of the circuit?
Solution:
Since the resistors are connected in parallel,
to calculate resistance of the circuit follow these steps
1/R = 1/R1 + 1/R2
1/R = 1/3 + 1/4
1/R = 4+3/12
1/R = 7/12
R = 12/7
R = 1.71 ohm
