Setting Up a Current Source: Parallel Resistances

Click For Summary
SUMMARY

To set up a current source, resistances must be placed in parallel rather than in series to allow current to divide appropriately across the circuit. In a series circuit, the current remains constant, which limits the functionality of the current source. The discussion also references Norton and Thévenin Equivalent circuits as foundational concepts in understanding current sources. Proper configuration is essential depending on the required current for the circuit.

PREREQUISITES
  • Understanding of parallel and series circuits
  • Familiarity with Norton and Thévenin Equivalent circuits
  • Basic knowledge of electrical current and resistance
  • Experience with circuit simulation tools
NEXT STEPS
  • Research the principles of Norton and Thévenin Equivalent circuits
  • Explore circuit simulation software for practical applications
  • Study the effects of resistance configurations on current flow
  • Learn about designing current sources in electronic circuits
USEFUL FOR

Electrical engineers, electronics students, and hobbyists interested in circuit design and analysis will benefit from this discussion.

To set up a current source why do we need to place the resistances in parallel rather than than placing them in series.
 
Engineering news on Phys.org
well I think that's because the current divides in the parallel circuit.

It would be same throughout in the series circuit, so there might be no use for a sonnection in the series. And it also depends on the amount of current needed through the circuit.

I think

Welcome to the PF. Are you asking about Norton and Thevinin Equivalent circuits?

yes
the very same

Ok, then did the link answer your question? And what do you mean by "set up" a current source? Do you mean in a simulation?
