what is bleeder current? n how to find it out?

If the load in the given circuit is 80 k

, what is the bleeder current?

 

[charmcaster.engg]

I find out the total equivalent resistance n then current comes to be 2.1mA. But ans. is 1.96 mA.?

Which component is the 'bleeder resistor'?

Which component is the 'bleeder resistor'?

The current flowing through an unloaded voltage divider is bleeder current.

It would seem that whoever calculated the answer of 1.96 mA was using a different definition.

Was the question to find the bleeder current, or find the current through the bleeder resistor?

I get 1.96mA through R2. I obtained this by first calculating the output voltage. It would then seem that the bleeder current is the wasted current through R2

Can you explain in detail how you have find out the current? I tried but I didn't get it.

The question is to find bleeder current. No additional details.

...explain in detail how you have find out the current...

Find the voltage across RL from the voltage divider between R1 and {R2 in parallel with RL}, then use that voltage to get the current through R2.

Thanks!
