Festival lights in buildings are an example of ____________.

Correct option is A

Correct Answer:(a) series circuit

Understanding Festival Lights in Older Systems:

·      Traditional festival lights (older designs) are often wired in aseries circuit.

·      In a series circuit, the current flows through each bulb sequentially, meaning all the bulbs are connected end-to-end in a single path.

Characteristics of Series Circuits in Festival Lights:

• If one bulb in the series fails or is removed, the entire circuit breaks, causing all the lights to go off.
• This design is simpler and was commonly used in earlier decorative lighting systems.

Electromagnetic Induction:

• This involves generating current through a coil by changing the magnetic field and is not relevant to the operation of decorative lights.

Magnetic Effect:

• While current in wires produces a magnetic field, it is not the primary mechanism for lighting operations.

A Parallel Circuit:

• Modern festival lights use parallel circuits for better reliability, but the question refers to older systems often using series circuits.

Booster Points:

Limitations of Series Circuits in Festival Lights:

o  Single Point Failure:If one bulb burns out or is disconnected, the entire string stops working.

o  Voltage Distribution:The voltage is divided among the bulbs, which can affect brightness.
