First of all , I'm a completely new to this current - voltage concept , I have problems understanding Grounding and the current flow in circuits . 1) Which path do currents take when there are multiple grounds in a circuit . 2) How and where should a circuit be grounded and why ? 3) Why is earth considered as an Infinite source /sink ? 4 ) If we use a "'metal plate "" in a circuit ( Would it get charged after the electrons flow to it from the battery ( Please bear with me , it might be a stupid question )) 4) If a circuit( consider a basic circuit , where there is a battery and a bulb ) When the grounding is done to this circuit ,Why wont the electrons from the Battery flow to the Ground ? Since Ground is considered as an infinite source/sink . 5) I have trouble understanding How battery eliminator works ( comparing it to chemical cells) . Thank you ! and Please help me .
