Problem 1-14: Current of A Voltage Source

Find the current passing through the voltage source:
a)
A voltage source in series with a current source
b)
A voltage source in series with a current source and other elements


Solution
a) The voltage source is in series with the current source. Since by definition a current source keeps the current passing through itself constant and the voltage source is in series with the current source, it should have the same current  10 A.

b) The same scenario is happening here and the voltage source has the same current as the current source  5A.

    1. It has effect on the current of the resistor (=5A+3A). The current of the voltage source is the current of the current source. By definition, a current source keeps the current of the line constant. Any component which is in series with a current source has the same current passing through itself.

  1. Dear Sir, I have a doubt ..
    1. What would be the maximum current that a voltage source can deliver?
    Say for eg. what would be the max. current of 230v source
    2. Also how that is decided (i mean on what factor)

    Also like this i have some basic questions in electrical engg.. where i cud i post them if u have time & willigness to reply?

    Thanks,

  2. in the given circuit is the both the sources are supplying power ? if so what happend if the terminals of voltage source is reversed

  3. Hello sir need help in a similar problem

    given circuit

    __________ 2A 2 ohm
    |Given |-------o ----------------- ( --> )----------^^^^^--------|
    | Network | +V ____ 5V
    | | - --
    |_________ | ------ o--------------------------------------------------|

    what would be value of V

    If we argue that the current due to current source is constant 2A then i get 9V as the answer ...is this correct.
