SERIES CIRCUIT

What happens to the entire circuit if one bulb 'blows' in a series circuit?

• Only that bulb goes out

• All bulbs go out

• Half of the bulbs go out

• The circuit continues to work normally

Answer explanation

Explanation: In a series circuit, if one component fails, it breaks the entire circuit as there is only one path for current to flow.

How does the current flow in a series circuit?

• Current varies at different points in the circuit

• Current is highest near the power source

• Current has the same value at any point

• Current splits between components

Answer explanation

Explanation: In a series circuit, there is only one path for current flow, so the current remains constant throughout the circuit.

What is the total resistance in a series circuit with three resistors of 2Ω, 3Ω, and 5Ω?

• 10 Ω

• 5 Ω

• 2 Ω

• 3 Ω

Answer explanation

Explanation: The formula for total resistance in series circuits is Rtotal = R1 + R2 + R3...

• Voltage does not affect the current

In the given figure, the voltage across R is :

• 9 V

• 21 V

• 13 V

• 17 V
