Yes. Overflowing raise temperature of connectors, and corrosion is heat-sensitive process.

What is a handle type switch?
what prevents excessive flow of current in a circuit
Circuit breakers are used for what?
Circuit breakers prevent excessive current from flowing in the circuit by "tripping" when the current exceeds the circuit breaker rating. This causes the current to be cut off, and is used to protect the wiring as well as the appliances.
What is the best indication of excessive current flow?
The best indication of excessive current flow in an electrical circuit is if a protective fuse blows or a circuit breaker trips.Fuses and circuit breakers are designed to open a circuit when an excess amount of current occurs, so as to break that flow of current.The worst indication of excessive current flow is if a length of cable overheats and/or catches on fire...Equally bad is if a piece of electrical equipment - or its power cord and/or plug - overheats and/or catches on fire...
How is an ammeter connected in a circuit in order to read the current flowing in the circuit?
In series with the circuit and never in parallel. The reason being that it will cause the circuit total resistance to drop which will make the circuit draw excessive current. That's a short circuit actually.
What causes a starter fuse to blow on a 04 expedition?
Over load in circuit? Remove starter and have it checked at auto parts for excessive current draw Dead short to ground in circuit? Over load in circuit? Remove starter and have it checked at auto parts for excessive current draw Dead short to ground in circuit?
Explain overloading in an electric circuit?
Excessive current can be in the connection of many devices into a single socket.this may cause overload in the circuit
How fuses differ from circuit breakers?
A fuse contains a component that melts or breaks in some other fashion when excessive current flows through it. This breaks the electrical circuit. A fuse that has functioned in this way can never be reused. A circuit breaker is a mechanical switch that opens, breaking the flow of electricity when the current goes above a set point. A circuit breaker can be reused by simply closing the switch again once the problem causing excessive current has been taken care of.
What happens in a short circuit occurs in an electric circuit?
A short circuit is a condition whereby a point or section of the circuit offer a short path for current to return to the power supply. It occurs when two or more points or sections of the circuit touches each others (but only and only if that results in drop in resistance to such an extent that it causes excessive current to flow through.
What will happen to the total current if you keep adding bulbs in parallel to the circuit?
Adding more lamps in parallel (across) a line will cause total current to climb. It will keep climbing (increasing) until a load protection device (circuit breaker or fuse) breaks the circuit or until something fails because of excessive current.
What component is constructed using a metal strip made of two different metals that will separate when current flow is excessive?
a circuit breaker
What 2 voltages is a short circuit made of?
Circuits are not made of voltages, they are made of loops. A short circuit exists when a connection is added that is not supposed to be part of the intended circuit as designed. This added connection produces extra loops in the circuit that typically prevent current from reaching parts of the circuit where it is needed and can cause excessive current to flow in other parts of the circuit, resulting in damage to the components in the circuit.
Why short circuit has very low resistancs?
A short circuit is defined: An unintentional connection of low resistance or impedance in a circuit such that excessive and often damaging current flows in it (from Wiktionary.org) Why a short circuit has very low resistance is very simple: because that's how "short circuit" is defined.
