If C is capacitance and V is Potential difference then unit of CV is: plz fast
Answers
Answer:
C=qV=qW/q=q2W=(AT)2ML2T−2C=qV=qW/q=q2W=(AT)2ML2T-2
[M−1L−2T4A2][M-1L-2T4A2]
V=[ML2T−3A−1]V=[ML2T-3A-1]
ρ=RaI=VIaI=(ML2T−3A−1)(L2)ALρ=RaI=VIaI=(ML2T-3A-1)(L2)AL
=[ML3T−3A−2]=[ML3T-3A-2]
From F=q1q24π∈0r2F=q1q24π∈0r2
in0=q1q24πFr2=(AT)2(MLT)−2(L2)=[M−1L−3T4A2]in0=q1q24πFr2=(AT)2(MLT)-2(L2)=[M-1L-3T4A2]
Now, CVρin0=qρin0CVρin0=qρin0
=AT(ML3T−3)(M−1L−3T4A2)=AT(ML3T-3)(M-1L-3T4A2)
= [A]
:. dimension of A = 1
Answer:
it is coulomb
Explanation:
according to the formula
Q = CV
here Q represents charge stored in capacitor and hence unit of charge is coulomb
dimensionally,
C = Aε₀ / d
where a is area
d is distance between the plates
and ε₀ is permitivity of free space
C =[ L² ] [M⁻¹ L⁻³ T⁴ A² ]/ [L]
= [ M⁻¹ L⁻² T⁴ A²]
V= [ M L² T⁻³ A⁻¹]
WHEN MULTIPLIED
CV = [ AT]
which is dimensionally charge and hence unit is coulomb
