Answer to Question #207173 in Physics for Adamson

Question

Explain how, using a capacitor in conjunction with a gold-leaf electroscope, the voltage sensitivity 

of the electroscope may be increased

Answer 1

1) Charge the capacitor with a battery

2) Connect the capacitor to the electroscope

3) Now, since there is already a charge between the capacitor plates, the golden leaves will deflect at even small charges.
