Experiment 2 — Series or Parallel?

Topic: Physics · Class 10 · Electricity: combinations of resistors

Aim: Wire three 6 Ω lamps so that each is fully bright and one failing does not switch off the others.

Daily: Your home is wired in parallel, which is why switching off a fan leaves the lights on. Old decorative light strings were in series — and one dead bulb killed the whole chain.

Question: Three identical lamps are wired in series and one burns out. What happens?

Exp: A series circuit has a single path, so any break stops the current everywhere.

Question: In a parallel circuit, each component receives…

Exp: Which is why home wiring is parallel.

Question: Three 6 Ω resistors in parallel give an equivalent resistance of…

Question: In series, the quantity that is the same everywhere is…

Exp: Voltage divides between the components.

Question: A fuse protects a circuit by…

Exp: It breaks the circuit before wiring overheats.
