HOW?

Pooja said: (Jul 21, 2011)  
Because the resistors will be parallel and thus resisitance will decrease. !

This is correct explanation.

How


Voltage divider is when resistance is connected in series.. And when load is connected to existing resistance in series then total resistance will be increased.

Yeah, I agree with @Prasanna. Only resistors in series are voltage dividers. In parallel, current is split but not voltage. So adding another resistor to series should increase resistance, not reduce.

Yeah, I agree with both @Prasanna and @Priyanka. Voltage gets divided in series circuits and current gets divided in parallel circuits. So definitely resistance will increase.

Voltage divider is a series resistors i.e,. divided into different voltages then resistance will decreases.

Vertically three resistors are connected from that voltage divider for example 555 timer circuit so resistance decreases.

Yes I agree with resistance is decrease.

Take a simple voltage divider circuit then you will get know total resistance decrease.

Yeah! the total resistance will decrease because,

V= IR.

And,
R = V/I.

Now I is not changing in series connection so V is proportional to R.

If voltage decreases then the resistance also be decreases.

Yes resistance will decrease.

What is the correct answer? Please explain.

Voltage divider is when resistance is connected in SERIES. And when LOAD is connected to existing resistance, usually LOAD RESISTANCE connected in PARALLEL. Hence the Resistance will Decrease.
