Key Concepts

Ideal Voltmeter

An ideal voltmeter measures the potential difference between two points without drawing any significant current from the circuit. This is accomplished by designing the meter with extremely high, ideally infinite, resistance, ensuring that its connection does not alter the circuit's original behavior.

Ideal Ammeter

An ideal ammeter is designed to measure the current in a circuit without altering the current flow. To achieve this, it is constructed with as little resistance as possible—ideally zero—so that it does not introduce any additional voltage drop or circuit disturbance during measurement.
