Electric Charges 
 
• Charge is an electrical property of the atomic particles of 
which matter consists, measured in coulombs (C). 
  
• The charge e on one electron is negative and equal in 
magnitude to 1.602 × 10
-19
 C which is called as 
electronic charge. The charges that occur in nature are 
integral multiples of the electronic charge.

Electric Current (1) 
 
• Electric current i = dq/dt. The unit of ampere can 
be derived as 1 A = 1C/s. 
• A direct current (dc) is a current that remains 
constant with time. 
• An alternating current (ac) is a current that 
varies sinusoidally with time.
