What is the mathematical relationship between heat dissipation and applied voltage?

Heat dissipation is directly proportional to the square of the applied voltage according to Joule's Law. This means that as the voltage increases, the heat dissipated in a circuit also increases quadratically. The relationship is represented by the formula: Heat dissipation = V^2/R, where V is the voltage and R is the resistance in the circuit.

What makes a current lower and generates more heat?

The resistance of the electrical conductor, eg a wire, reduces the current which can flow in the circuit. The remaining current which does flow generates heat, representing the electrical energy which has been lost in overcoming the resistance.


What is the relationship between resistance and voltage in an electrical circuit?

In an electrical circuit, resistance and voltage are directly related. According to Ohm's Law, voltage is equal to the product of resistance and current. This means that as resistance increases, voltage also increases, and vice versa.


What is the heat dissipation loss formula?

The heat dissipation loss formula is typically given by the equation: Heat Dissipation Loss = I^2 * R where I is the current passing through the component and R is the resistance of the component. This formula is commonly used to calculate the amount of heat generated and lost by a resistor or any other electrical component due to the flow of current.
