Question

write the definitions,units and formulas of the following terms
1)current
2)potential difference
3)resistance
4)resistivity
5)ohm's law​

Answer 1

Answer:

*Current is the rate at which electrons flow past a point in a complete electrical circuit. At its most basic, current = flow. An ampere (AM-pir), or amp, is the international unit used for measuring current.

*the difference of electrical potential between two points.

*the ability not to be affected by something, especially adversely.

*Resistivity, electrical resistance of a conductor of unit cross-sectional area and unit length. A characteristic property of each material, resistivity is useful in comparing various materials on the basis of their ability to conduct electric currents.

*law stating that electric current is proportional to voltage and inversely proportional to resistance.
