Which of the following units denots the dimensions `ML^2 // Q^2` where Q denots the electric charge ?

A

Henry (H)

B

`H//m^2`

C

Weber (Wb)

D

`Wb//m^2`

Text Solution

Verified by Experts

The correct Answer is:
(a)
Henry is unit of self- indcutance (L). From
`e = (L dI)/(dt)`
`L = (edt)/(dI) = ((W//q)dt)/(dI)`
`=[ML^2 T^(-2)]T/(QA) = ([ML^2 T^(-2)]T)/(Q Q//T)`
`i.e., = Henry (H) = ML^2 // Q^2`

Find the dimensional formulae of a the charge Q. the potential V, c. the capacitance C and d the resistance R. Some of the equations containing these quantities are Q=It, U=VIt, Q=CV and V=RI, where I denotes the electric current, t is time and U is energy.

The rate of flow of charge in a circuit is called electric current. In other words, it is the amount of charge flowing per second. It is denoted by the letter I. If Q is the charge which is flowing through a conductor in time t, then current is given by i = Q/t Unit of current: The S.I unit of current is ampere and it is denoted by the letter 'A'. The S.I unit of Q is coulomb and that oft is second. Thus, the S.I unit of electric current is ("1 coulomb")/("1 second") = 1A How much time is required for 10 coulombs of charge to flow past a point if the rate of flow (current) is 2 amperes?
