Answer:
7) Resistance is the property of a conductor to resist the flow of current through it.
Its S.I. unit is ohm
Answer:
7.Resistance is the property of a conductor to resist the flow of current through it. Its S.I. unit is ohm, represented by the Greek letter ohm
8.Magnetic Flux Density is amount of magnetic flux through unit area taken perpendicular to direction of magnetic flux. Flux Density (B) is related to Magnetic Field (H) by B=μH
9.Minerals are naturally occurring inorganic solids with a crystalline structure and a definite range of chemical formula. Ores are concentrations of minerals in rock that are high enough to be economically extracted for use. All ores are minerals, but all minerals are not necessarily ores.
10.catenation is the bonding of atoms of the same element into a series, called a chain. A chain or a ring shape may be open if its ends are not bonded to each other, or closed if they are bonded in a ring. The words to catenate and catenation reflect the Latin root catena, "chain".
11.
Ohmic conductors are those which follows the ohm's law. Eg resistor. Non ohmic conductors are those which don't follow ohm's law. Eg bulb filament.
12.i.the difference of electrical potential between two points
ii.a difference in potential that tends to give rise to an electric current.
