Question

write Ohm's Law? define 1 Ampere?​

Answer 1

1:-Ohm's Law--It is the resistance between two points of a conductor under a certain set of circumstances. There must be a constant difference of potential (the work required to bring a unit of electric charge) of 1 volt applied .

2:-1 Ampere-- between these two points, producing the conductor a current of 1 ampere.

Substance: Resistivity (r); (ohm-meter)

Rock Salt: 30 - 1 x 1013

Mica: 9 x 1012 - 1 x 1014

Sphalerite: 1.5 - 1 x 107

hope it helps you.............................

thanks

Answer 2

Ohm's law :-

as long as the physical state of the conductor remains unchanged, the potential difference across the conductor is directly proportional to the current flowing through that conductor.

V is directly proportional to I

1 Ampere:-

if 1 columb flows through the conductor in 1 second then the current flowing in that conductor measures 1 ampere.

that's your answer freind!!!!
