The voltage drops occur when the current passes through each of the resistors and the total voltage drop for the entire circuit is equal to the sum of the voltage drops through the three resistors. The current through each of the resistors must be exactly the same because the current in a series circuit is the same everywhere.
It is possible, however, for something to happen that causes the wire bringing the current in to come into contact with either the wire carrying the current out or the ground wire, thus causing what i...It is possible, however, for something to happen that causes the wire bringing the current in to come into contact with either the wire carrying the current out or the ground wire, thus causing what is called a short circuit. When the switch is in the on position, electricity can flow through the red circuit, through the electromagnet, and out into the rest of the circuit.
