Question 4

Three identical lamps are each labelled 240 V, 60 W. They are connected to a 240 V electrical supply.

In which of the following arrangements do all three lamps operate at their normal brightness?

A

All three lamps are connected in series across the 240 V240\text{ V}240 V supply.

B

All three lamps are connected in parallel across the 240 V240\text{ V}240 V supply.

C

Two lamps are connected in series, and this group is connected in parallel with the third lamp across the 240 V240\text{ V}240 V supply.

D

Two lamps are connected in parallel, and this group is connected in series with the third lamp across the 240 V240\text{ V}240 V supply.
