please I need an explanation of what it means when we say that cirrent (I) is proportional to voltage (V)...
Thanks

It means that when you increase the voltage across a component, the current through the component is also increased, with a direct linear proportion.

Ohm's law tells us the relation ship between voltage, current and resistance. V = IR
where V = voltage, I = current and R = resistance.
When two things are proportional, it means that they have a direct dependence on each other - in other words, if one gets bigger, then the other gets bigger. If one gets smaller then the other gets smaller. Voltage and current have this kind of relationship.

You can visualize it as increasing the pressure (voltage) in a pipe (circuit) which will increase the volume of fluid (current) flowing through it.
