# Question about Voltage and Current

After reading texts, I am confused with Voltage and Current. As per Ohms law, V = IR.

When texts explain for a given circuit, they always talk in terms of voltage not current especially V(out) in case of voltage divider. Why is that? I get confused at this point.

For Leg1 and Leg2, output voltage will be the same but current going through output will be very different. If, for example, output needing high current would work from LEG2 but not LEG1.

Can somebody explain when OUTPUT (Vout) is considered in a given circuit does that mean it's an output to 2nd stage and designers must consider voltage instead of current?

Voltage and current both have to be considerations.  In your circuit, you show where the outputs are located but you don't show what the output load is.  In that situation we can calculate the output voltage using the voltage divider rule but output current cannot be calculated because we don't know the load.

In your circuit you say one leg provides more current than the other leg.  If we make some presumption about the load value, this can be calculated.  Also, without knowing the load value, you can short the output to ground and calculate a maximum current value for the sake of comparing the two legs.  I hope this helps.
