Question

which of the units represent ampere? 1. coulumb second 2. volt ohm 3. volt ohm -1 4. volt -1 ohm​

Answer 1

Answer:

(1) Coulomb : It is a quantity of electricity obtained when one ampere current flows for one second.

It is the unit of quantity of electricity.

Q = I × t Coulomb (C)

Where Q is the charge or quantity of electricity in coulombs.

(2) Ampere : It is a strength of an electric current obtained when one coulomb of electricity is passed through a circuit for one second.

∴ I = Q/t

(3) Volt : It is the potential difference between two points of an electric conductor required to send a current of one amphere through a resistance of one ohm.

∴ V = I × R

Where V is the potential difference in volts and R is the resistance of a conductor in ohms.

(4) Joule : It is the electrical work or energy produced when one coulomb of electricity is passed through a potential difference of one volt.

∴ Electrical work = Q × V J

Where Q is electrical charge in coulombs and V is the potential difference.

(5) Ohm : It is the resistance of an electrical conductor across which when potential difference of 1 volt is applied, a current of one ampere is obtained. It has units, Ω or per siemens.
