Question

define
1.1 ampere
2. volt
3. 1 ohm
4. 1 watt

Answer 1

HEY HERE IS YOUR ANSWER..

AMPERE-It is a unit of current equal to a flow of one columb per second.

VOLT-It is the unit for measuring the electrical force.

OHM-It a unit for measuring electrical resistance.

WATT-It is a unit of electrical power.

Answer 2

Demonstration model of a moving iron ammeter. As the current through the coil increases, the plunger is drawn further into the coil and the pointer deflects to the right is called ampere.
volt
One volt is defined as the difference in electric potential between two points of a conducting wire when an electric current of one amperedissipates one watt of power between those points.[2] It is also equal to the potential difference between two parallel, infinite planes spaced 1 meter apart that create an electric field of 1 newton per coulomb. 
1 ohm
1ohm is the unit of resistance . It is equal to 1 volt upon 1 ampere. It means that an object having a resistance of 1ohm allows 1 ampere of current to flow through 2 points having potential difference of 1 volt.
1 watt
1 watt is the power of an agent, which does work at the rate of 1 joule per second. OR. Power is 1 watt when the rate of consumption of energy is 1joule per second.
