A motor is connected in the main part of a circuit. The wire then divides into two branches. One branch contains lamp S and the other branch contains lamp T. The branches rejoin before returning to the cell.
The filament in S breaks.
Which statement describes the motor and T?
The broken filament prevents current in the shared part of the circuit, so the motor stops but T remains lit.
The motor continues to work because it is before the split, but T goes out when either branch is broken.
The break removes every complete route through the cell, so both the motor and T stop working.
A complete route still runs through the motor and the branch containing T, so the motor continues to work and T remains lit.
