All three wires, the "hot", neutral and the ground must all maintain the integrity of the circuit. This is why pigtails are connected from the main circuitry to the receptacle or switch devices so that they can be removed without opening the electrical circuit.
To receive a shock from electrical devices you have to become part of the electrical circuit. Most electrical devices come in two categories. One, the device is grounded and the other is the device is double insulated.The grounded devices have their metallic frames grounded. On a short circuit fault this will trip the breaker and isolate the device's fault before you have a chance to ground out the device by touching it.The double insulated device has two covers that protect the user from shock. The double insulation type of protection is usually used on hand held power tools.
Yes a circuit will work without a switch but the only problem will be is that electricity will be wasted and there will be no device to stop the flow of current
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.
A fuse is intended to be a weak link of thin wire that goes in series with a circuit. If the current becomes too high for any reason, the fuse wire melts and cuts off the supply. Without a fuse, the circuit will heat up until something else melts, which might cause a fire. So fuses are necessary to prevent electrical fires.
hot swapping
A complete electrical circuit occurs when it is possible for electrical current to flow through the electrical devices in it.
You can't unless you connect with a friend's DS and then you can save without shutting down
If you are referring to an electrical circuit, a series circuit is wired in such a way that if one object is removed from the circuit, the circuit is broken and everything within the circuit loses power. In a parallel circuit different components of the circuit can be removed without disabling power to the rest of the devices within the circuit.
saves battery power without shutting down
The bulb is the load of the circuit, without it you have a short circuit.
