Describe static electricity

Static electricity is the buildup charge in an insulated object

Define electric current

Electric current is carried by the electrons from a negative to positive source

What is the symbol for electric current

I

What is the unit of measurement for electric current and its symbol

Ampere represented by A￼

Describe Conventional current flow

Conventional current flow from positive to negative source. due to continue use this direction of charge becomes an established convention ￼
