•
Com a outra mão submergir o corpo de prova (por
exemplo, o bastão friccionado) para o recolhimento
da sua carga total no espaço interior livre de campo
do copo de Faraday e “despojar” a carga na lateral
interna do copo.
•
Calcular a carga cedida segundo as relações e
equações a seguir:
•
Entre a carga Q e a tensão U de um condensador
com a capacidade C existe a relação:
U

•
Devido a U

a tensão de saída do eletrômetro
é uma medida para a carga Q:

Com a conhecida capacidade C = 10 nF do
condensador U8403501 pode-se agora calcular a
carga.
