Define electric potential , potential difference , ohm's law and electric current with their SI units ?
Answers
Explanation:
- An electric potential is the amount of work needed to move a unit of charge from a reference point to a specific point inside the field without producing an acceleration. Typically, the reference point is the Earth or a point at infinity, although any point can be used..
- Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points.
- Ohm's law is a law that states that the voltage across a resistor is directly proportional to the current flowing through the resistance. Ohm's law is named for German physicist Georg Ohm (1789-1854). A simple formula, Ohm's law, is used to show the relationship of current, voltage, and resistance.
- Ampere is one of the SI base units for electric current.

Answer:
ELECTRIC POTENTIAL
An electric potential is the amount of work needed to move a unit of charge from a reference point to a specific point inside the field without producing an acceleration
POTENTIAL DIFFERENCE
the difference in potential between two points that represents the work involved or the energy released in the transfer of a unit quantity of electricity from one point to the other
OHM'S LAW
Ohm's law is a law that states that the voltage across a resistor is directly proportional to the current flowing through the resistance. Ohm's law is named for German physicist Georg Ohm (1789-1854). A simple formula, Ohm's law, is used to show the relationship of current, voltage, and resistance.
ELECTRIC CURRENT WITH SI UNIT
The SI unit of electric current is the ampere or amp, which is the flow of electric charge across a surface at the rate of one coulomb per second. The ampere (symbol: A) is an SI base unit Electric current is measured using a device called an ammeter.
