Question

Which one of the following is false with respect to stray capacitance?

(a) Reduces with decrease in size of lead wires

(b) Reduces when chip capacitors are used

(c) Increases when lead wires a are lengthy

(d) Increases with less capacitance value

I had been asked this question in a job interview.

Asked question is from Tuned Circuits topic in portion Fundamentals of Electronics of Avionics

Answer 1

Correct answer is (d) Increases with less capacitance value

To elaborate: The lead wires of capacitors behave as a complex RLC circuit and generate stray capacitance. This can be reduced by shortening the length of the lead wires or using chip capacitors. However, decreasing or increasing the value of capacitance does not affect stray capacitance.
