Subject Physics
The street lamps are connected in parallel.
Q
Figure 7 shows how the National Grid transfers energy from a power station to some street lamps.
Why is the current in each street lamp less than the current in the secondary coil in
transformer Y?
Tick () one box.
Current is used up in the cables between Y and each street lamp.
Some of the current is dissipated to the surroundings.
The cables between Y and the street lamps have electrical resistance.
The street lamps are connected in parallel.
