1.	The strength of a dielectric is defined as the maximum electric intensity which it can withstand. A parallel-plate capacitor of plate area A on one side is filled with a dielectric of strength E and permittivity ε. The maximum charge which can be given to the capacitor is (a) εEA (b) EA/ε (c) E/εA (d) εE/A
Answer» Correct Answer is (a) εEA Let K = dielectric constant, ε = ε₀K. σ = Q/A E = σ/ε₀K or Q = εEa

Answer»

Correct Answer is (a) εEA

Let K = dielectric constant, ε = ε₀K.

σ = Q/A E = σ/ε₀K or Q = εEa
