Class 12 Physics simulations · Current Electricity

Wheatstone bridge

Adjust four resistors and bring the galvanometer reading to zero.

Open the simulation

What to notice

At balance, the two bridge midpoints have equal potential and no current crosses the detector.

Key relation

Balance: P/Q = R/S

Try this

Change one resistor, then restore the balance ratio.

What you can change

• Resistance P: 10 to 100 Ω
• Resistance Q: 10 to 100 Ω
• Resistance R: 10 to 100 Ω
• Resistance S: 10 to 100 Ω
