ViviAn ampere (A) is a unit of electric current, measuring the rate of flow of electric charge. Ohm (Ω) is a unit of electrical resistance, measuring how much a material resists the flow of current. In simple terms, amps measure the flow of electricity, while ohms measure the resistance to that flow.

What is definition of one ohm?
One ohm is the SI unit of electrical resistance, representing the resistance of a conductor in which a current of one ampere is produced by a potential difference of one volt. It is named after the German physicist Georg Simon Ohm.
What is the breakdown of the ohm units?
The ohm unit measures electrical resistance. It is represented by the symbol . The breakdown of the ohm unit is as follows: 1 ohm is equal to 1 volt per ampere. This means that if a voltage of 1 volt is applied across a circuit and it produces a current of 1 ampere, then the resistance of the circuit is 1 ohm.
What are the base units of the ohm, and how are they defined in the context of electrical resistance?
The base units of the ohm are the volt and the ampere. In the context of electrical resistance, the ohm is defined as the resistance that limits the flow of electric current when one volt is applied across it and one ampere of current flows through it.
What is the difference between microamps and milliamps?
The main difference between microamps and milliamps is their size. Microamps are one millionth of an ampere, while milliamps are one thousandth of an ampere. In other words, a milliamp is larger than a microamp.
What scientist discovered that potential difference is equal to current multiplied by resistance?
Georg Simon Ohm, a German physicist, formulated Ohm's Law in the 19th century. Ohm's Law states that the potential difference (voltage) across a conductor is equal to the current flowing through it multiplied by the resistance of the conductor.
