Question

Joule/ coulomb is the same as [ ]
a) 1 - watt
b) 1 - volt
c) 1- ampere
d) 1 - ohm

Answer 1

Answer:

(b)1volt

Explanation:

1volt=1joule/1coulomb

Answer 2

Joule / Coulomb is ame as 1 volt (option-b).

• Joule and coulomb are the SI unit of work and charge respectively.
• And, the volt is the SI unit of potential difference or voltage.
• And, voltage or potential difference is the ratio of work done and the charge
• The mathematical expression for V:

        Voltage or potential difference, V = work done(W) / charge(Q)

         V = W / Q

• In terms of SI units:

        1 volt = 1 joule / 1 coulomb

         1 V   =  J / C
