Qmax = C * Vmax = C*d*(V/d)max
= C*d*(dielectric strength)
= 37*10^-12 F *0.006 m * 3.2*10^7 V/m
= 7.1 *10^-6 Coulombs
since 1 Farad*Volt = 1 Coulomb
How did you go from
C * Vmax
Q max = c *Vmax = C*D* (V/d)max
did you just divide and multiply C*V with d so that you end up with dielectric strength (V/d)
In going from
C * Vmax
I just multiplied and divided by d at the same time (no change) and put one of the d's under the Vmax
Vmax/d is the electric strength, in volts per meter.
Perhaps you were confused by my writing it as (V/d)max . It means the same thing. For a given d, there is a maximum V.
Oh okay I understand now, you just made it equivalent to get E = V/d
