What are the advantages of 3 pin plug?
The three prong plug incorporates a ground wire for safety. If there is a short circuit in an appliance that has a three prong plug, the current will travel back to the electrical panel and either blow the fuse to that circuit, or trip the circuit breaker to shut power down on that circuit.
Why would you get a shock when unplugging an appliance that is turned off - I accidentally touched the metal prong on the plug as I was unplugging it - Was this why?
The switch to the appliance is down stream from where the power comes in from the plug. Even though the appliance is turned off at the switch the appliance has electricity up to the switch. As you stated there will be voltage potential right up until the pins of the appliance become disengaged from the receptacle If you have ever noticed a three blade plug, the ground pin is longer that the hot and neutral blades. What this accomplishes is that when plugging in a device the ground is made first and when un-plugging the ground is the last to be disconnected. By holding the appliance you were at the same ground potential as the appliance. By touching the "hot" side of the plug when pulling it out you became the return path for the electricity to flow. If you had touched the neutral side of the plug when pulling it out you would have felt nothing. Be careful when removing plugs from receptacles. Always pull on the plug body and never on the appliance's cord
How to tell if 1964 240 V stove plug is tripping the circuit breaker or is the circuit breaker bad?
You may need to call in an electrician, or appliance repairman.See view discussion below.
An appliance plug can be distinguished from other plugs by its?
permanent attachment to an appliance An appliance plug may have a differently shaped plug, in order to prevent it from being plugged into an ordinary electrical outlet (one with the wrong voltage or power rating).
What happens when you plug 120vac appliance into a 30 amp line?
Most 30 amp home circuits are 240 V. If you try to run a 120 V appliance using 240 V, the appliance will immediately self-destruct.However... if you actually have a 30 amp 120 V line to which you want to plug in your appliance, the only issue would be fire protection. Circuit breakers are in place to prevent too much current from passing through a wire. Wires have the capacity to carry only a specific amount of maximum current. a 10 Ga wire is generally used in homes for a 30 amp circuit. It doesn't matter if it's carrying 120 or 240 V, it still needs to be a 10 AWG conductor.However, you need to make certain that all conductors, outlets and circuit breakers are matched to each other when wiring a home or business.The appliance will only use the amperage that it needs UP TO THE MAXIMUM RATING OF THE CIRCUIT, providing that the VOLTAGEmatches.So the short answer is, just make certain that the line voltage is right for your appliance and that the circuit is rated at a high enough amperage to handle the appliance.
If an appliance does not work at all when you plug it in and turn the switch on the appliance circuit is what?
The appliance's circuit is open.

Should you pull the plug out of the wall socket when not in use?
There is no need to. You can just switch it off. Only pull the plug out if your doing electrical work on the appliance. Otherwise, there is no need to take the plug out; just switch it off.
Can you plug a 125-250 appliance into a 120-240 circuit?
all voltage is plus or minus 10% of rating

When you pull out the plug connected to an electrical appliance you often observe a spark to which property of the appliance is this related?
I think it is due to the resistance to the electrical appliance, the resistance offered by the electrical appliance works as a load in the circuit and when load is removed it causes sparking.
Can you plug in a 110v spa into a residential outlet?
If it's rated at 110 then you can safely plug it in to a residential outlet. But, because it is generating heat, it will be drawing substantial voltage so you should ensure that the appliance is on its own circuit; otherwise when someone else turns on a light, or plugs in another appliance, the circuit will overload and shut down.

What will happen to the appliance if there is a short circuit to the cable supplying it?
Electricity takes the path of least resistance - That is to say most of the electricity takes the path of least resistance.In this case the short circuit will have an incredibly low resistance, and the vast majority of the electricity will bypass your appliance, causing no damage (to the appliance) at all. However where the short circuit occurs on the cable one will find burning marks and heat damage, perhaps even part of the metal has been vaporised leaving a hole or melting mark on the metal of the wire itself.There is also a very good chance the fuse will break inside the plug top and that circuit breakers* will trip in your board.*Breakers because the fault current may be large enough in a short circuit to trip your main circuit breaker and not just the breaker for the circuit the appliance is plugged into, this however is rare.
What happens if you plug a 120V appliance into a 240V outlet?
You will burn up your appliance!!!!!

Why would some lights in your house blink and not the others?
It is most likely caused by another appliance on the same circuit. When a heavy draw on the circuit is caused by an power consuming appliance, the voltage will tend to drop lower that what it was before the current draw. This is the condition that you see as the lights dim or as you call it blinking. The same thing happens when a motor load is applied to the circuit. It can be seen when fridges and freezers start their cycle of starting. If it is a plug in appliance that you think is causing this condition plug it in some other circuit and see if it happens there. If it does then it is nothing to worry about. If it is the same circuit time after time you should get an electrician to look at the problem as it might be the start of something else and it is better to catch it early rather than later.
