What happens when 110 volt equipment is plugged into a 240 volt source?

Answer

You should assume that any appliance or motor designed for 110 operation and plugged into a 240 volt circuit will rapidly self destruct.

But ...

However, as more and more people travel and visit other countries with various mains voltages, there is a new generation of consumer electronics which is specifically designed to operate on a wide range of power inputs (which usually includes 110-240 volts). So you might not notice the difference! Check the equipment rating plate - it should have one.

Answer

an electrical surge and then the 110 bolt is plugged in a higher voltage it doesnt work permanently. it doesnt work because it can only handle 110 volts thats why they give them a voltage because if u plug to a higher vcoltage it gives it tooo much juice and it cant handle it so it dies

Answer

Let's look at a simple resistive circuit. The amount of current flowing through the circuit is proportional to the voltage divided by resistance: V = IR. R will remain constant, as it is a trait of the load. So, as the voltage doubles, the current flowing through it doubles. Each part of a system dissipates power. Power is the product of voltage and current. Since P = IV and V = IR, P = RI^2. Thus if the current flowing through a component doubles, the amount of power dissipated by that component quadruples!

So let's say you have a 120W light bulb. This bulb has 120 ohms of resistance and normally draws 1A at 120V. Now let's say that you hook this bulb up to 240V. Now it is drawing 2A, and is dissipating 480W. Since the bulb is not designed to dissipate that much energy, the weak points burn open.

So, when you connect a load to a voltage outside of it's rated input, you increase the energy dissipated by it to a value outside of it's operating range. This causes component failure in the form of "burning out."

Answer

It's simple, the smoke comes out, the innerds self-destruct, and you have a pile of fried, dead, elctronics.

Answer

What happens in this instance depends upon what type of equipment it is and how it is designed. Sometimes nothing more happens than a circuit protective device is tripped or blown. In consumer electronic equipment, often the primary winding of the power transformer (if the device is so equipped) will be blown open. These two events can occur without further damage to the circuitry, depending upon how well the other components can absorb a short voltage spike. I have replaced fuses and power transformers in amplifiers that suffered no further damage. Sometimes the fuse or primary winding does not blow open quickly enough, and other components can suffer catastrophic damage. In the case of a solid state guitar amplifier, this generally means that the output transistors will overload and short. Other components may also be affected; it is difficult to know in each case exactly what will happen. In summary, plugging a 110 volt device into 220-240 does not necessarily mean that it is "fried" and is unrepairable, but it also does not mean that any 110 device plugged into 220-240 can or should be repaired.
