Voltage Controlled Current Source

If magnitude of current is controlled through input voltage then the source is known as voltage controlled current source.

Current Controlled Current Source

If magnitude of current is controlled through input current the source is known as current controlled current source.

Example :                       

Solution:

            Given figure indicates that across a resistor of 3k, a battery of 10 V has been applied, therefore by Ohm's law the current flowing by it, might be given as

            Basic Formula                         I =V/R

                                                             =10/3k

                                                             = 3.33 mA         Ans.
