In a lighting circuit an open circuit will turn off the light.
Nothing. An open circuit means no current is flowing. When the circuit is closed, current flows, the filament of the bulb is heated by the current and glows, giving off light. But when the circuit is open, nothing happens.
It is a relay or switch problem. A circuit breaker or fuse won't keep a light on.
The electrical circuit when turned on it is considered closed. By the same token when an electrical circuit is turned off the electrical circuit is considered open.
If an appliance does not work at all when you plug it in and turn the switch on the appliance circuit is not on.
bulb burned out; fuse/circuit breaker open
bad fuse or short to ground or an open circuit
When you turn on a light switch you do not have an open circuit.
We usually see a thermal fuse that has failed open the primary circuit to the high voltage transformer, which in turn drives the magnetron in that appliance.

if you turn the selector switch of your aircon and only fan is working and no cold air coming out of the diffuser have your aircon fuse connected to the compressor check. If the fuse is not blown then have your thermostat be set to colder position. If the compressor still does not work have the thermostat be check by an auto aircon tech. If the thermostat is ok then look for any sign of oil in the piping of your aircon system possibly there is leak which causes the pressure switch not to function. If theres no refrigerant in the system the compressor will not be activated by the pressure switch.
First thing you do is turn off the power to that circuit. Then replace the fuse
The appliance's circuit is open.
I'm not sure what you mean by "breaker". If you mean fuse, then yes, there is a turn signal fuse in the circuit.
Fuse #7 is the turn signal circuit. 10 AMP. 2nd fuse fron the left in the 2nd row from the top.
Circuit 2 is the fuse box located at the bottom of the left-hand side front door pillar. Just turn the set screw 1/2 turn to remove the cover. You probably have a blown or missing fuse.
