Ampere : The ampere is a measure of the amount of electric charge in motion per unit time ― that is, electric current. But the quantity of electric charge by itself, whether in motion or not, is expressed by another SI unit, the coulomb (C). One coulomb is equal to about 6.241 x 1018 electric charges (e).

Electric Resistance : Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). ... Insulators: Materials that present high resistance and restrict the flow of electrons.

Electric Charge : An electric charge is the property of matter where it has more or fewer electrons than protons in its atoms. Electrons carry a negative charge and protons carry a positive charge. Matter is positively charged if it contains more protons than electrons, and negatively charged if it contains more electrons than protons.In SI base units: C = A⋅s

SI unit: coulomb

Other units: elementary charge; faraday; ampere hour
