and
do you have the units for , and ?
can some one help with this formula please i need to find 2 unknowns
A area and d distance
Formula is
C = Er*Eo*A / d
where
C= 100x10 power-12
Er=12
Eo= 8.85x10power-12
i can isolate d/A to equal Er*Eo/C which makes d/A = 1.062 ohms
and get d= Er*Eo*A / C
but brain wont go any further
any help much appreciated
thanks Ian
hello there that was a quick reply thanks!
the units are
C= 100pico farads
Er is relative permittivity of 12 (ratio no units)
Eo is relative permittivity of air 8.85x 10power-12
A in Meters ie but very small area
d in metres but likely around 1mm or less
as its to do with capacitors
thanks Ian
