A coil of wire inculed with voltage. This voltage is called induced voltage and it is induced due to the change in magnetic flux of the coil. If we take a current carry wire, a magnetic field will be there due to flow of current. If we change the current of wire, magnetic flux will … Read more

If you are talking about a typical and properly wired electrical circuit in a house, the black is the hot wire, the white is the neutral and the bare copper wire is the ground.

The current in such a circuit is alternating. The white wire will have the same voltage as the black wire if the … Read more

I don't know for sure, but I would certainly not plug them in while the computer is plugged in and running. I'm honestly confused as to why you need to consider doing something like this...? It's not something I've ever thought about doing for any reason. I asked my PC guru and he said the … Read more

The reason to shut off the electricity to the heater is for shock reasons. The temp adjustments (2) are at the upper and lower coils. Risk of shock is great at these two points. Your heater is on a 220v breaker. If you are unsure, just shut off the main breaker in your box. That … Read more

A parallel circuit is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit. Each load connected in a separate path receives the full circuit voltage, and the total circuit current is equal to the sum of the individual branch currents.

Im going to take it that youre talking about chain saws here which the chain pump is an internal pump that lubricates the saw blade itself everytime it spins so it cuts cleaner and easier and saves wear on the chain itself
