The symbol for charge is \(Q\), it is measured in coulombs (\(C\)). The symbol for current is \(I\), it is measured in amperes (\(A\)). The symbol for time is \(t ...

One coulomb of charge is equivalent to 6,250,000,000,000,000,000 electrons. In a closed circuit that includes a source of potential difference (voltage) there will be a current flowing around the ...
