Question

how is the electric potential difference between two points defined?state its s.i unit

Answer 1

In electromagnetism, we use a positive charge to define electricfields. ... Electric potential difference is the difference inelectric potential between two points in space. That's really all itis. It is also measured in Joules per coulomb, but this is usually shortened to a different unit: volts.

Answer 2

hey dear!!

-------------------------!!
_________________!!

Electric potential difference between two points is defined as work done to move per unit charge from one point to the other in a current carrying conductor.

Thus,potential difference = Work done /charge.

=>1 V = J / c

thus, 1 V = 1 J C ^-1.


So,S.I. unit of electric potential difference is Volt .It is denoted by V.

Potential difference between two points is measured by using an apparatus called voltmeter.

This device is always connected in parallel between two points where p.d. is to be measured.
