Question

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

Answer 1

Answer:

volt

Explanation:

the unit of potential difference is J/C or volt.

hope it helped and pls mark as brainliest:)

Answer 2

answer : option (b) 1 - volt.

explanation : let's find the dimension of Joule/coulomb at first.

we know, dimension of Joule = [ML²T-²]

dimension of coulomb = [AT]

so, dimension of J/C = [ML²T-²]/[AT]

= [ML²T-³A-¹] .......(1)

now, find the dimension of each option.

option (a) watt , we know, watt is unit of power .so, dimension of watt = [ML²T-³]

option (b) volt, we know , volt is unit of potential difference. so, dimension of volt = dimension of energy/dimension of charge [ as we know, formula, qV = workdone/energy ]

= Joule/coulomb = [ML²T-³A-¹], this is the correct choice. [ see eq. (1) ]

option (c) ampere, it is the unit of current . ampere can't be same as J/C.

option (d) ohm, it is the unit of resistance. it is also not possible.

hence, option (b) 1 - volt, is same as J/C
