In a series circuit, what happens if any resistor is broken or a fault occurs?
In a series circuit, what happens if any resistor is broken or a fault occurs?
- The voltage across each resistor increases
- The current flow is branched out
- The entire circuit is turned off (correct)

What is the formula to calculate the total resistance in a series circuit?
What is the formula to calculate the total resistance in a series circuit?
- Rtotal = R1 × R2 × …..× Rn
- Rtotal = R1 + R2 + …..+ Rn (correct)
- Rtotal = R1 - R2 - …..- Rn
- Rtotal = R1 ÷ R2 ÷ …..÷ Rn
