Question

If the dielectric constant and dielectric strength be denoted by $k$and $x$ respectively, then a material suitable for use as a dielectric in a capacitor must have

• A. High $k$and high $x$
• B. High $k$and low $x$
• C. Low $k$and low $x$
• D. Low $k$ and high $x$

Answer 1

Answer: (A)

High $k$and high $x$

Answer 2

High K means good insulating property and high x means able to withstand electric field gradient to a higher value.
