→ The circuit below has two capacitors and a 12 V battery.
Capacitor C, is filled with air, and the other C₂ is filled
with a dielectric for which the dielectric constant is 3;
both capacitors have a plate area of 5 x10³ m² and a
plate separation of 2 mm. (5 points)
G
(The answer given here is given with C, without a dielectric, and C₂
with a dielectric.)
12. Find the capacitance of C₁.
C₁-AE/d= 2.21x10¹¹¹ F
