Differences between Series and Parallel Circuits

Criteria

Series

Parallel

Voltage Drop

Different across each element

Same across each element

Current

Same through each element

Different through each element

Resistance

Total Resistance = R1 + R2 + R3 + …. Rn

1/Total Resistance = 1/R1 + 1/R2 + …..1/Rn

Fault

If any element fails, currents stop flowing in the whole circuit

If an element fails, current stops flowing in that particular branch only.

What is the Difference Between Series and Parallel Circuits?

To understand the difference between series and parallel circuits, let us first define what a circuit is.

An electric circuit is defined as a closed loop of conducting elements through which current can flow. An electric circuit basically consists of the following components:

  • Voltage or a Current source
  • Connecting wires
  • Elements like Resistors, Capacitors, Inductors, transistors, diodes, etc.
