Key Concepts

Electromotive Force (emf)

Electromotive force is the energy provided per unit charge by a battery or other energy source. It represents the ideal voltage that exists in the absence of load and internal resistance, acting as the driving potential for the movement of electric charges in a circuit.

Internal Resistance

Internal resistance is the inherent resistance within a battery that causes a voltage drop when current flows. This resistance reduces the terminal voltage available to an external circuit compared to the battery’s emf, and its effect becomes more significant at higher currents.

Terminal Voltage

Terminal voltage is the actual voltage output available from a battery when current is drawn. It is determined by subtracting the voltage drop caused by the internal resistance from the battery’s emf, making it a key factor in assessing the battery’s performance under load.

Ohm's Law

Ohm's Law is a fundamental principle that relates voltage, current, and resistance in an electrical circuit. It is used to calculate the voltage drop across an internal resistor or any resistive element by expressing that voltage as the product of the current flowing through the resistor and its resistance.

Electrical Power

Electrical power quantifies the rate at which energy is transferred or converted in a circuit. When considering a battery, it is typically calculated as the product of terminal voltage (or emf in some contexts) and the current drawn, providing insight into the performance and efficiency of the power supply.
