# Name of this electrical circuit?

nivaOne
Hi,

I'm woundering whether this circuit has some kind of dedicated name in the field?

It's not just the average voltage divider as it it influences the serial part as well the parallel part in the same time.
And does anybody know when it is typically used?

Thanks,

NivaOne

Rp is set up as a voltage divider driving RB as a load.

Looks like Rp is a potentiometer....like Simon said above, looks like a voltage divider, where the voltage across Rb can be anywhere between 30 and 0 volts, and in between the extremes, the voltage resulting from the voltage division between Rp and Rb.

I think it is commonly referred to as a Manually Controlled Variable Potential Reduction Demonstrator. (just kidding)

I don't really see how you could get 30 V across the load with this set-up. If it is indeed a potentiometer, than Rp can either be in series with the load or in parallel with the load, or somewhere in-between. Either way, Rp would have to be zero and in series for 30 V to appear across the load. My apologies if I am wrong.

If a potentiometer is adjusted to its top adjustment the series resistance will be zero. Rp will appear in parallel with Rb

Right. My apologies! My head was in a book all day, so I for some reason was not comprehending that.

Not a Red Dwarf fan then?
Hybrid Electromotively Adjustable Thermal Efficiency Reducer.
... that goes on the right, if the adjustment is not electromotive then it has to go on the left.
