Abstract
To measure a resistance value in a circuit by conventional method, one side of the resistor should be disconnected from the circuit, then an Ohmmeter is connected across the resistor. To measure a current through a component, one side of the component should be disconnected and an ammeter is connected between the 2 open terminals. As such mentioned above, measuring a resistance value or a milliamp current value is very inconvenient with a conventional multimeter. With the present invention, a voltage, a current, and a resistance can be measured altogether at the same time automatically without manually disconnecting a component in a circuit with 2 or more resistors connected in series.
