Current And Resistance Relation
A multimeter is a multipurpose device that can measure current in addition to voltage and resistance.
Current and resistance relation. Ohm defines the unit of resistance of 1 ohm as the resistance between two points in a conductor where the application of 1 volt will push 1 ampere or 6 241 10 18 electrons. The relationship between current and resistance is derived from the definition of the ohm and not from ohm s law. This brings us back to georg ohm. To measure current in a circuit an ammeter must be inserted inside the circuit.
The circuit with the higher resistance will allow less charge to flow meaning the circuit with higher resistance has less current flowing through it. This electronics video tutorial provides a basic introduction into voltage current and resistance. For measuring current one can use an ammeter which measures the electric current only or uses a multimeter. The first and perhaps most important the relationship between current voltage and resistance is called ohm s law discovered by georg simon ohm and published in his 1827 paper the galvanic circuit investigated mathematically.
The unit of voltage is the volt which is a measure of el.
