A: If you are lucky a fuse blow or a circuit breaker opens up. If not a fire maybe started in the walls where is hard to see and put it out. In the USA the outlets are implemented to be used with a 15 amperes total. By drawing more current continuously the wiring get hot because of the current passing to the load if sustained for too long a fire may start. It is preferable to short out the outlet because that will insure a fuse blow or a circuit breaker open up continuous overload is very dangerous

If you don't plug in any extension cords, then the distance remains the same. Resistance of copper does not vary much as it heats up slightly. However, it will approximately DOUBLE when heated to near the ignition temperature of paper. Many ordinary wires are only provided with insulation that will survive boiling water temperatures, not much higher.
The amount of power DISSIPATED in that same resistance, however, increases exponentially with the current increase. P = I x E, E = I x R, P = I^2 x R (where R, as mentioned, is fixed for ordinary usage).
Double the current and it will quadruple the amount of power (heat). Overload the circuit to a high temperature and the resistance doubles, which also doubles the amount of power being used (converted to heat), creating a runaway condition.
That's why we have "circuit breakers" and fuses: to keep the wires from becoming overloaded and heating up.

What happens to the overall resistance of a circuit when too many appliances are connected across a 120 V outlet?
This is a very technical electrical question that may be difficult to understand without further study. But adding appliances to an outlet is the same as adding resistance in parallel. Adding resistance in parallel, the resistance of the circuit goes down. That is why you get more current flow. By contrast, adding resistance in series increases the resistance of the circuit and therefore reduces current, all else being equal.
What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
What happens when the parts of the circuit are properly connected?

If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
What happens when an electric current encounters resistance?
An electron traveling through the wires and loads of the external circuit encounters resistance.
What happens to supply voltage if additional resistance is connected in parallel circuit?
No change in supply voltage as additional resistance is connected in parallel circuit.

When resistance is in a circuit what happens to the current?
When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.
When a dead short occur what happens to circuit resistance?
The circuit resistance is likely to gradually drop and in such case it will cause the circuit to burn down.
What happens if you shorten the resistance wire in a circuit?
It shortens
What happens to amps when you increase the resistance of a circuit?
If you don't change the voltage between the ends of the circuit,then higher resistance in the circuit means lower current (amps).
What happens when a fuse burns out when overloaded with too many appliances?
the circuit is broken.
What happens in a circuit?
A short circuit is one that is characterized by extremely low resistance. This will result in the extremely dramatic increase of current. High current will flow until a safety device opens the circuit, or the weakest link in it burns out. And one of the two usually occurs in a moment or two.==Short Circuit happens when the cables of the electrical appliances are worn out or it's not connected properly,a short circuit may occure.A short circuit has a very low resistance that almost all electric current flow through it.It'll affect the operation of the electrical appliances.Owing to the heating effect,the excess electric current would produce a large amount of heat,wihout a fuse or a circuit breaker,a fire may be occured when there's a short circuit.
What happens the power consumption of a circuit as its resistance increases?

What happens to a parallel circuit resistance if the voltage applied is doubled?
That has no effect on the resistance. The current doubles also.
