True or False: Overloads and short-circuits will bring about increased temperatures within the electrical circuit.

The statement is true because both overloads and short-circuits lead to an increase in temperature within an electrical circuit due to excessive current flow. In the case of an overload, the electrical demand on the circuit exceeds its designed capacity, causing parts of the circuit, such as wires and components, to carry more current than they are rated for. This excess current generates heat, which can lead to overheating and potentially cause damage or failure.

Similarly, short-circuits create a pathway for current to flow with very low resistance, often resulting in a rapid and significant increase in current. This surge in current also generates excessive heat, which can quickly escalate to hazardous levels, posing serious risks such as fires or damage to the electrical system.

Understanding these concepts is crucial for maintaining safety standards in electrical work and ensuring that circuits are protected against damage from overloads and short-circuits.
