Find the current through the 5 volt source by simplifying the resistors to a single equivalent resistance.


The 10 and 20 are in parallel (because the tops and the bottoms are connected so that they share the same voltage) and the 30 and 40 are in parallel.

Now the two resistors are in series, so:
We can compute the current using Ohm's law,

I = V/R = 5 V / 23.81ohms = 210 mA
