SUMMARY

The discussion focuses on determining the voltage at various points in an electrical circuit using a practical model. Participants established that the voltage at point A is +25 V due to a voltage source, while point B is calculated at 24.3 V, accounting for a 0.7 V drop across the diodes in the circuit. The voltage drops across the diodes are consistent, leading to further inquiries about calculating the voltage at point C and point D, which remain unresolved in the discussion.

PREREQUISITES
  • Understanding of basic electronics concepts, including voltage sources and diode behavior.
  • Familiarity with practical circuit analysis techniques.
  • Knowledge of voltage drop calculations in series circuits.
  • Ability to interpret circuit diagrams and voltage references.
NEXT STEPS
  • Study voltage drop calculations in circuits with diodes, focusing on practical models.
  • Learn how to analyze circuits using Kirchhoff's Voltage Law (KVL).
  • Explore methods for determining voltages at multiple points in complex circuits.
  • Investigate the behavior of diodes under different current conditions and their impact on circuit voltage.
USEFUL FOR

Electronics engineering students, circuit designers, and anyone involved in practical circuit analysis and voltage determination in electronic systems.

Both the diodes are in on state and in this condition the voltage drop on them is $V_{d} \sim .7 V$ no matter which is the current... Kind regards $\chi$ $\sigma$
 
I don't understand. the question is asking for the voltage with respect to the ground.:confused:

Let's start with point A.
There is a voltage source between ground and point A.
Its voltage is 25 V.
Therefore the voltage at point A is +25 V.
 
point B is 24.3v. because the voltage drop across the diode is 0.7v so 25-0.7v=24.3 v

but i don't know how to determine the voltage at point c.

Good!

but i don't know how to determine the voltage at point c.

Let's do point D first then...
 
but how?:confused:
