Measuring Voltage In A Series Circuit

It should read in the vicinity of 8 3 v.

Measuring voltage in a series circuit. Set your multimeter to measure dc voltage and get ready to take some measurements. For example you can insert a voltmeter into the led circuit so that you can measure voltage. The red lead of your multimeter should be at a higher voltage than the black lead so take care to orient the probes as described. For the 2 ohm resistor the voltage would be 1 2 times 2 or 2 4 volts.

To measure voltage in more complex circuits we can use the voltage divider rule. Connect a voltmeter or multimeter across individual component of the circuit as shown below. The supply voltage is shared between components in a series circuit so the sum of the voltages across all of the components in a series circuit is equal to the supply voltage v s. 9 v batteries rarely provide a full 9 v to measure voltages in the led circuit spin the multimeter dial to a range whose maximum is at least 10 v.

In this case the voltage is measured across the battery. The ammeter is in series with the lamp measuring. First measure the voltage supplied to the circuit by the battery pack. An ammeter is a measuring device used to measure the electric current in a circuit.

This rule only applies to series circuits that have more than one load component. You need to know how to measure the current that flows through a component in a circuit and the voltage across it. A simple electrical circuit contains a source of voltage a power supply such as a battery generator or the utility wires coming into your building a wire to carry current in the form of electrons and a source of electrical resistance in reality such circuits are rarely simple and include a number of branching and re joining points.
