Q: The work done across two points having 10 V potential difference is 30 J. So the electric charge flowing between the two points will be-
  • A. 3 ohms
  • B. 3 joules
  • C. 3 coulomb
  • D. 3 amperes
Correct Answer: Option C - Given, Potential differential, V = 10 V Work done, W = 30 J, The electric charge flowing between the two points Q = W / V = 30/10 = 3 coulomb Hence the electric charge flowing between the two points will be 3 coulomb
C. Given, Potential differential, V = 10 V Work done, W = 30 J, The electric charge flowing between the two points Q = W / V = 30/10 = 3 coulomb Hence the electric charge flowing between the two points will be 3 coulomb

Explanations:

Given, Potential differential, V = 10 V Work done, W = 30 J, The electric charge flowing between the two points Q = W / V = 30/10 = 3 coulomb Hence the electric charge flowing between the two points will be 3 coulomb
