Name the physical quantities of which the units are
(I) Volt (ii) coulomb (iii) ohm (iv) ampere
Answers
Answer:
volt =(i) Volt is the electrical unit of voltage or potential difference (symbol: V). One Volt is defined as energy consumption of one joule per electric charge of one coulomb. (ii) The SI unit of electric charge is coulomb (symbol: C). One coulomb is the amount of charge in one ampere-second.
coulomb = Answer: The 'physical quantity' whose S.I unit is (i) coulomb/volt is capacitance and for (ii) newton/coulomb is electric field and for (iii) joule/coulomb is electric potential.
ohm = One coulomb is the amount of charge in one ampere-second. (iii) The SI unit of electrical resistance is Ohm (symbol: Ω). The ohm is the equivalent of a volt per ampere. (iv) The SI unit of electric current is Ampere (symbol: A).
ampere = The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. Electric current is measured using a device called an ammeter.
