Hi, sorry that I didn't explain. I thought I had written enough to clear it already.

In parallel circuit, load share current, while in series they share voltage.

Yeah that is right. Loads share current in parallel. But which current? The current supplied by the source is being shared.

But how much current does a load consume? That is dependent on the impedance/resistance of the load at a specific voltage. If the voltage doesn't change, no matter how many loads you connect in parallel, a load will consume only the current that needs. If we add more loads in parallel, that would stress the source, but not the other loads in parallel as far as the voltage of the source is constant.

Say you have a 5 ohms resistance connected across a 10V batter.

Current through the branch = 10/5 = 2A

Now add another 5 ohms in parallel.

The voltage across both the resistances are 10V itself, right?

So both will consume 2A each. But now, the load will have to supply 4A in total to supply the needs of both loads. If we remove a load, again the voltage is 10V, and current to be supplied by the load reduces to 2A.

We can add as many branches in parallel till the total current supplied by the load increases to its rated value. It wouldn't affect other loads.
