 Mathematically, current is represented as:  Mathematically, current is represented as: 
  
-$$ i=\frac{dq}{dw}\         (Eq. 1.2) $$ +$$ i=\frac{dq}{dt}\         (Eq. 1.2) $$ 
  
 Where //i// is the current in amperes, //q// is the charge in coulombs, and //t// is the time in seconds. Thus, current is the time rate of change of charge and units of charge are coulombs per second, or //amperes// (abbreviated as //A//).  Where //i// is the current in amperes, //q// is the charge in coulombs, and //t// is the time in seconds.
