Blowing voltage regulators
Lets look at a circuit with a few branches.
If the battery positive is at 12 Volts above ground, what is the voltage at the switches?
If that is difficult. Imagine the battery is a pressured air tank at 12 Pa, and the switches are valves preventing the pressurized air from escaping. What is the pressure at the valves?
Like pressure, voltage only drops when electrical flow experiences resistance. You disconnect the only branch of the circuit where current was flowing, and you get a situation like above.
Close two of the switches and what happens?
The electromagnet sees 11 Volts and the lamps see 10.6 Volts.
The voltage dropped as current tried to flow through the poor connections.
Similar to pressure drops when pushing water or air through a pipe that is too small.
No current flowing so there is no drop in voltage.
