because electrical loads r connected in parallel always and when hence the effective resistance decreases and so current increases

Ya... Joe is right... Here I'm just elaborating whatever Joe has provided.

The electrical loads are normally connected in parallel, whenever the load(impedance) is increased means the additional load (or you can say impedance) is connected in parallel to the existing load. The parallel combination always reduces the equivelent impedance. Hence the current is increases.

Simple Example: let suppose a 10 ohm resistance is connected to the 10 V battery then the current drawn by the load will be 1 Amp. Now increase the load, let us suppose additional 10 Ohm resistance is added into parallel. The total resistance will be 5 Ohm of this parallel combination and the current flow from the battery terminals will be 2 Amp, hence we can say on increasing load current drawn by the load increases.

The reason behind this is that all devices are connected in parallal fashion..so when we increase the load,the effective resistance of the circuit decreases, and so the current drawn from supply increases

When we Increase Load, Current drawn from Source is also Increases,because when we Switch ON the System or Electrical  Equipment Current will Flow through the System. So, the Current will Increases & Load on the Same will Increases.

Because, the load's are in parallel, if you switch on load due to parallel, total effective resistance decreses. Thus I=(V/R) according to OHM's law relationship the current drawn from the source increases.

When we increase the power of our load, and since power=v*i therefore the load which is connected to a constant voltage source will fetch more current to operate at its rated power consumption.

Increase in load means, we are utilising more power , and the voltage of many systes is almost constant. so for increasing power current will increase.

when we increase the load current increases because when load is increased power consumption increases and
p=sq.root3.V.I.cos q.
according to the expression, voltage & p.f. remains the same for a particular system. hence when load increase current increases.

OR

in other words we can say that load is current only............
