# Grounding a conducting object

Is it possible to trap some electricity in the object even though the object is grounded? For example if we ground a conducting sphere over a resistor, will all electricity leave the sphere once it's grounded?

let's say the sphere now gets charged, will it become neutral ? I apologize for asking such a simple question.

The sphere acts as a capacitor of value $C$ charged at a voltage $V_0$ = $Q\over C$ relative to ground. When you connect the resistor it will discharge towards zero (relative to ground) exponentially, at a rate dependent on the RC product.
$v(t) = V_0 \cdot (1 - e^{-t/\tau})$ where $\tau = R \cdot C$
