Resistors in Parallel – Class 10 Science Experiment
Resistors in parallel is an essential concept in understanding how electric circuits behave when multiple resistors are connected across the same voltage. In this configuration, each resistor is connected directly across the power supply, and the total current is divided among the resistors.
Understanding the Concept of Resistors in Parallel
When resistors are connected in parallel, they each experience the same voltage across them, but the total current in the circuit is shared. This is commonly used in household wiring systems, where devices operate independently of each other.
In such a configuration:
-
The reciprocal of the total or equivalent resistance (R) is equal to the sum of the reciprocals of individual resistances.
That is:
(1/R) = (1/R1) + (1/R2) + (1/R3) + …
Where:
-
R1, R2, R3 are the individual resistances connected in parallel.
-
R is the equivalent resistance.
-
-
The voltage (V) across each resistor is the same.
-
The current (I) through each resistor is different, depending on its resistance.
According to Ohm’s Law:
I = V/R
For parallel circuits:
-
The total current is the sum of individual currents through each resistor.
-
As more resistors are added in parallel, the total resistance decreases, allowing more current to flow through the circuit.
This behavior makes parallel circuits efficient for ensuring that devices can operate even if one path is broken—another critical advantage of using this configuration.

Frequently Asked Questions
-
What happens to total resistance when resistors are connected in parallel?
The total resistance decreases as more resistors are added in parallel. -
Do all resistors in parallel get the same voltage?
Yes, the voltage across each resistor in a parallel circuit is the same. -
How is current divided in a parallel circuit?
The current divides inversely with resistance; more current flows through the path with lower resistance. -
