ohm's law states that, at constant temperature potential difference is directly proportional to current

1. According to OHM'S LAW,

The Current flowing through a conductor is directly proportional to the Potential Difference across the cross-section of the conductor providing physical quantities (like temperature) remain unchanged.

2. The rate of Energy required to move electrons is called POWER.

3.A pause or restriction or prohibition provided by the conductor to the current flowing through it is called RESISTANCE.

4.If 1A of current is flowing through a conductor in 1s then the charge is said to be of 1 Coloumb.

5.The difference in the potential of the end points of the conductor is called POTENTIAL DIFFERENCE.

6.If 1J of work is done to move 1C of charge then the potential difference across the cross-section of the conductor is said to be of 1 VOLT.

7.If 1A of current is flowing across 1V of potential difference then the resistance offered by the conductor is said to be of 1 OHM.

Hope this will help you.

luckiestgirl: can i know the units for 1.current. 2.electric charge. 3.work. 4.resistivity
Shardul27: Ya sure why not
Shardul27: 1.Ampere(A) 2.Coloumb(C) 3.Joules(J) 4.Ohm-metre(_o_-m)
Shardul27: Ohm's symbol you know na It has not been made clearly
Shardul27: These are S. I units
