Answer 1

Answer:

C =  362.85 pF

Explanation:

Capacitor consists of two metal plates each of 10 cm by 20cm they are separated by two millimetre insulator with dielectric constant 4.1 and dielectric strength 6.0 × 10 to the power 7 volt per metre what is the capacitance in picofarad

C = Kε₀ A / d

k = 4.1

ε₀ = 8.85  × 10⁻¹² F/m

A = 10 * 20 cm²  = 2 * 10⁻² m²

d = 2 mm = 2 × 10⁻³ m

C = (4.1 × 8.85  × 10⁻¹² × 2 * 10⁻²) / (2 × 10⁻³)

C = 362.85 × 10⁻¹² F

C =  362.85 pF
