Viva Questions and Answers

Q1: What is a series circuit?

A: A series circuit is a circuit where resistors are connected end-to-end, so there is only one path for current to flow.

Q2: How do you calculate the total resistance in a series circuit?

A: The total resistance in a series circuit is the sum of all individual resistances.

Q3: What happens to the current in a series circuit?

A: The current remains the same through all components in a series circuit.

Q4: How is the voltage distributed across resistors in a series circuit?

A: The voltage is divided among the resistors proportionally to their resistances.

Q5: If you have three resistors, R1 = 2Ω, R2 = 3Ω, and R3 = 5Ω in series, what is the total resistance?

A: The total resistance is 2Ω + 3Ω + 5Ω = 10Ω.

Q6: Why do resistors in series have a higher total resistance than any individual resistor?

A: Because the resistances add up, increasing the overall opposition to current flow.

Q7: What is the formula for Ohm's Law?

A: Ohm's Law is V = IR, where V is voltage, I is current, and R is resistance.

Q8: How would you measure the total resistance of resistors in series using a multimeter?

A: Connect the multimeter probes across the combination of resistors and read the total resistance directly.

Q9: Can the total resistance in a series circuit ever be less than the smallest resistor in the series?

A: No, the total resistance in a series circuit is always greater than the largest individual resistor.

Q 10: What effect does adding more resistors in series have on the overall circuit resistance?

A: Adding more resistors in series increases the overall circuit resistance.
