Assuming you are talking about electrical circuits:

"Cell" is the name given for a battery. Without a cell in the circuit, there is no supply of electricity. Therefore there is no electric circuit.

Can a short circuit current through a photo cell damage it?

If the photo cell was on during the short circuit then the chances of damage to the photo cell are at a minimum. If the short circuit occurred when the photo cell was operated then yes damage to the internal contacts of the photo cell could have happened. What happens is, the short circuit is downstream from the photo cell and when the contacts of the relay close in the photo cell the dead short is applied to the contact faces of the relay. This is somewhat like striking an arc with a welded with the same results, the contact faces weld close and the circuits breaker trips to open the short circuit. With the pole faces of the photo cell's relay closed it gives the illusion that the photo cell is not operating. The photo cell's circuitry will be working but the relay will not drop the circuit open because of the welded contact in the relay.


Explain why the boiler and pump are a model for the cell in a circuit?

think of a circuit with a cell , wires and a bulb. now think about a boiler and pump, pipes and a radiator. the cell is like the boiler and pump because it has the energy. the pipes are like the wires because they transfer the energy. the bulb is like the radiator because they use the energy changing it into light energy and heat energy when referring to them especially.
