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.
One volt is defined as the electric potential difference between two points when one joule of work is done per coulomb of charge moved between them. It quantifies the energy transfer and electric force experienced by a charge in an electric field. Mathematically, 1 volt (V) is equivalent to 1 jouleRead more
One volt is defined as the electric potential difference between two points when one joule of work is done per coulomb of charge moved between them. It quantifies the energy transfer and electric force experienced by a charge in an electric field. Mathematically, 1 volt (V) is equivalent to 1 joule (J) of work done per 1 coulomb (C) of charge:
1 V = 1 J/C

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,Read more
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.
