Load
This is what the purpose of a switch is. It connects the "hot" wire to the load. When this is done the load becomes energized.
The term switch leg really means switched leg. It is the wire that comes off of the bottom terminal of a switch and when the switch is turned on becomes hot. This is the leg that turns the load off and on.
yes
The line supply connects to the top terminals of the switch and the load connects to the bottom terminals of the switch.
The switch will use no wattage whatsoever. The load on that switch is what uses power. If you know the load is 5 amps then 5 amps at 120 volts is 600 watts.
The relay's coil(s) would be a load, but the main function of a relay is to act as a switch to control power to a larger load.
It enables you to switch off the load from the socket, rather than have to pull the plug out of the socket.
It allows you to disconnect the load without having to unplug the flexible cable.
A switch is a make - break device. Its function is a circuit is to make and break the current flow of the circuit that it is in. This action then starts and stops the load that is connected in the circuit.
To open or close a single wire connection between a power source and a load.
On load switching is when a switch can be operated whilst current is still passing through the switch (i.e. it is on load) Offload switching is when a switch is operated whilst there is no current through the switch (i.e. it is offload)
No load is the least destructive load to a switch.
A relay is basically a controllable switch that connects a supply voltage to a load. If the relay is switch such that the load is not connected, that could be considered an open load. If it is switched the other way the load will be connected to its supply voltage. A defect in a relay would be something that caused it not to function correctly. It could be in the switch portion of the supply portion of the relay. Hence you are referring to different things and a defect may or may not cause the load to be open.
No, a switch is not considered a load in an electrical circuit. A switch controls the flow of electricity to the load (such as a light bulb or motor) by opening or closing the circuit. The load is the component in the circuit that consumes the electrical energy.
This is what the purpose of a switch is. It connects the "hot" wire to the load. When this is done the load becomes energized.
No it is not considered a load. A load transforms electrical energy into other types of energy :)
The load will be zero after the switch is turned off. if power is still being drawn then the switch is quite likely faulty
