Find the total resistance which will be = 9.2kohm
Total current is =2.15mV
Bleeder current is current through resistor R2 which is= 1.96mA
Use the formula current through r2= rL/(r2+rL)
(80/88)*2.15 = 1.95454545

Can you please the Bleeder current?

Here bleeder current is the current on R2 in the absence of load resistor RL. It means bleeder current is the unloaded current on the specific resistor where load is to be connected.

Why we are use 88?
How to come please anyone give me explanation?

Here, RL + R2 = 88.

As R2 AND Rl are parallel.
> 80x8/80 + 8 =7.2 kohm.
As R1 is in series with the above combination,
>7.2 kohm + 2kohm =9.2 kohm.
Total current I=V/R =20/9. 2 Kohm =2. 173 ma.
Next, current through R2= Ix Rl / Rl +R2 = 1.976 = 1.96 (approximated to).
