Question

Choose the incorrect relation among the following:
  1. Ampere = coulombsecond
  2. Volt = coulombjoule
  3. ohm = VoltAmpere
  4. 1coulomb=6.25×1018electroncharge

A
1coulomb=6.25×1018electroncharge
B
Volt = coulombjoule
C
ohm = VoltAmpere
D
Ampere = coulombsecond
Solution
Verified by Toppr

Ampere = SI unit of current =Charge(Coulomb)Time(Second)
Volt = SI unit of Potential =Work(Joule)Charge(Coulomb)
Ohm = SI unit of Resistance =Potential(Volt)Current(Ampere)
1 Coulomb=(1.6×1019)1 electron charge
=6.25×1018 electron charge
Option B is incorrect.
