Overloading in electrical circuits can result from factors beyond direct contact of live and neutral wires. One common cause is the simultaneous operation of high-power appliances, exceeding the circuit’s capacity. Poor wiring, loose connections, and damaged insulation increase resistance, leading to excessive heat buildup and overloading. Faulty appliances, short circuits, or malfunctioning devices can also contribute. Additionally, inadequate circuit design and insufficient distribution of loads amplify the risk. These factors collectively elevate current levels, potentially causing overheating, fire hazards, and damage to devices. Proper electrical planning, usage management, and regular maintenance are essential to prevent overloading.

To maintain current in an electric circuit, a cell needs to continuously provide a potential difference (voltage) across the circuit. It accomplishes this by undergoing chemical reactions within its electrodes and electrolyte. The cell expends chemical energy stored in its reactants, converting it into electrical energy. During this electrochemical process, electrons flow from the negative electrode (anode) to the positive electrode (cathode), creating a potential difference. The continuous chemical reactions sustain the voltage, allowing the cell to supply the necessary electromotive force to maintain the current flow in the circuit.

When a cell is connected to a conducting circuit element, such as a wire, the chemical reactions within the cell’s electrodes and electrolyte produce an electric current. At the anode, electrons are released during oxidation reactions, creating a surplus of electrons. Simultaneously, at the cathode, reduction reactions accept these electrons. The flow of electrons from the anode to the cathode through the external circuit constitutes the electric current. Ions within the electrolyte facilitate charge balance. This continuous electrochemical process generates a potential difference, or voltage, driving the flow of electrons and establishing a current in the connected circuit element.

The potential difference in a metallic wire, or electric pressure, is created by an external electric field or voltage source. When a voltage is applied across the wire, it establishes an electric field that exerts a force on the electrons within the conductor. Electrons experience a drift in the direction of the electric field, creating a net flow or current. In response to the voltage, electrons move from the region of higher potential (negative terminal) to the region of lower potential (positive terminal), establishing the flow of electric charges. This movement of electrons is essential for the conduction of electricity in metallic wires.

Gravity plays a negligible role in the flow of electric charges in a metallic wire. In metallic conductors, such as copper or aluminum wires, electric current is primarily driven by the electric field established by an applied voltage. The force due to gravity on electrons is extremely weak compared to the electric forces involved. While gravity does exert a force on electrons, the magnitude is much smaller than the forces influencing electron movement within a conductor. Therefore, the impact of gravity on the flow of electric charges in a metallic wire is essentially negligible in comparison to electric field-driven forces.

A fuse prevents damage in electrical circuits by interrupting the flow of current in case of overloading or short-circuiting. Comprising a thin wire made of a material with a low melting point, the fuse is connected in series with the circuit. During normal operation, the current heats the wire insignificantly. However, in case of excessive current, as in overloading or short circuits, the wire quickly overheats and melts, breaking the circuit and stopping the flow of electricity.
