A=2.0m? 45 V d-3.0 mm K-323.0 mm b) Submit Request Answer

Explanation / Answer

Solution:

Part c) We know, C= A epsilon not/ d = 2 * (8.85*10^-12) /0.003= 5.9*10^-9 Farad (Ans)

Part a) Charge Q= CV = (5.9*10^-9)*45 =2.65*10^-7 C (Ans)

Part d) Energy stored= 1/2 CV^2 = 0.5*(5.9*10^-9)* 45^2

=5.97*10^-6 Joules (Ans)
