    Could anyone give me an idea on how to apply Kirchoff's laws to a circuit containing a current source? For instance if I have a current source in paralel with a load and a voltage source than the resistance of the branch containing the current source would be equal to 0 so the voltage source is short-circuited. :unsure:???
    What is the voltage on a branch containing only a current source. Should i always use source transformation to deal with current sources?
    Please help me.

    The voltage drop across a current source is usually not 0. If the battery is in parallel with the current source then the voltage drop across the current source is the same as the voltage supplied by the battery.

    If the current source is in parallel with the resistor, the voltage drop across the resistor equals the voltage drop across the current source.
