What happens when two electric wires touch?

Answer: If the two wires are at different voltage levels, a short circuit is created when they touch each other. When you bring the two wires closer to each other, at one point, the gap is so low that the air between the wires is ionised and it breaks down, allowing a spark between the two surfaces.

Can AC wiring be used for DC?

So, the general principle of any such substitution of AC for DC cable is that that it’s ok to do when using the substituted cable at a lower voltage than rated. If the ratings are the same, or closely similar, then substituting an AC cable with a DC one might not matter.

What happens if you wire two circuits together?

With two wires connected to the same breaker or terminal, the circuit breaker could overheat. If the two wires are not fastened tightly enough, this could result in arcing. A fire may also occur if your circuit breaker is double tapped. You may be able to view for yourself whether your circuit breaker is double tapped.

Whats the difference between AC and DC wire?

Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically.

What happens if ground touches neutral?

If the neutral breaks, then plugged in devices will cause the neutral to approach the “hot” voltage. Given a ground to neutral connection, this will cause the chassis of your device to be at the “hot” voltage, which is very dangerous.

What would happen if a neutral wire touches any other part?

With neutral wire touching any other part, the shock may be fatal. In DC you will get a current to pass through your body when you complete the circuit between positive and negative, but the amperes of current will depend on the entire circuit resistance. AC-> Imagine getting consecutive punches of the current 100 times a second.

What happens when two wires touch in a circuit?

In any case, if two wires (or any conductive contact) at different potentials (the fancy word for voltage that applies here), touch there is now a new circuit. Each old circuit now looks like a power source and a resistor (technically a complex impedance, but more on that later).

What happens when we connect an AC circuit with DC supply?

This shows that excessive current will flow in the circuit if we connect an AC machine or device with DC supply which leads to burn the rotor or stator coils. If they survive, they wont be able to operate at normal condition. Another case is that AC circuits using capacitor where we know that a capacitor blocks DC and let pass AC through it.

What happens if an AC line touches a DC line?

Generally, the residential and home supply voltage is 120V AC (230V in EU) and 3-18V DC in case of electronic circuits. If accidentally AC line touches the DC line connected to the electronic circuit and components, the result may be bad smell smoke, flames or even worse.
