Whats the difference between load and load resistance?

Note:

In Practical Applications battery voltage is lowered as load increases.

Or

In Practical Applications battery voltage is lowered as load Resistance decreases .

Both are correct. Hope Understood meaning of Load and Load resistance.

V is proportional to I means V/I=constant. Again, V=IR or, V/I=R. So if the load R increases and keep the current constant, then V also increases.

If the resistance increase then gragually current decerease. So that think logically that whn resistance increase thn load incerase in the wire so rate of current is to be slow.

@rajasekhar-

Current is the rate at which electric charge flows past a point in a circuit. In other words, current is the rate of flow of electric charge.
Voltage, also called electromotive force, is the potential difference in charge between two points in an electrical field. In other words, voltage is the "energy per unit charge”.

Electrical energy gets dissipated as heat through load.(more precisely electrical energy gets converted into heat energy) more the load more energy is spent battery certainly loose energy very fast.

Example: the battery in your digital watch will run for a long time, when you connect the same set of battery to a completely resistance load like a LED light it will drain with in minutes. Energy dissipation in that watch was less but in LED it was more, more energy was spent to drive the LED.

(more the load more the power dissipation. Its a natural phenomenon no need to break it through ohms law)

Battery voltage gets lowered when load increases.

Consider you as battery and load as sack lifted by you

When ever number of sacks(Load) increases your energy(battry voltage) decreses gradually.

Think practical as we increase load current will draws more rapidly.

It is just like a inverter when ever the power supply is on it will get charged and as soon as the power supply goes off the battery will be enabled and the stored charge will decay exponentially
