Class 12 Physics simulations · Current Electricity

Series and parallel resistors

Compare equivalent resistance for two connection types.

Open the simulation

What to notice

Parallel paths reduce equivalent resistance below either branch resistance.

Key relation

Series: R₁+R₂; parallel: R₁R₂/(R₁+R₂)

Try this

Use equal resistors and compare series with parallel.

What you can change

• Resistor 1: 2 to 30 Ω
• Resistor 2: 2 to 30 Ω
• Connection: choose Series, Parallel
