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 resistors are interconnected in a circuit?
The net resistance can be found out using the algebraic sums f series and parallel connections. When there is no current flowing in the circuit the net resistance is infinite.

What happens to supply voltage if additional resistance is connected in parallel circuit?
The supply voltage in a parallel circuit remains the same regardless of the number of additional resistors connected. The voltage across each resistor in a parallel circuit is the same as the supply voltage. Adding more resistors in parallel will increase the total current drawn from the supply.
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 length of the wire in the series circuit is increased?
Increasing the length of wire in a series circuit increases the overall resistance in the circuit, which reduces the current flowing through the circuit. This results in a decrease in the brightness of any connected bulbs or the speed of any connected motors, as the components receive less energy due to the increased 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.
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.
What happens if you shorten the resistance wire in a circuit?
It shortens
What happens when a fuse burns out when overloaded with too many appliances?
the circuit is broken.
What happens when the parts of the circuit are properly connected?

What happens the power consumption of a circuit as its resistance increases?
😉
What happens to amps when you increase the resistance of a circuit?
When you increase the resistance in a circuit, the current (amps) in the circuit will decrease. This is because Ohm's Law states that current is inversely proportional to resistance, so as resistance increases, current decreases.
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.
