Circuit with 2 voltage sources and 1 current source

Click For Summary

Discussion Overview

The discussion revolves around analyzing a circuit with two voltage sources and one current source. Participants are focused on determining the voltage across each resistor and the currents i1 and i2 using Kirchhoff's laws.

Discussion Character

  • Technical explanation

Main Points Raised

  • One participant presents their calculations using Kirchhoff's Current Law (KCL) and Kirchhoff's Voltage Law (KVL) to find the currents and voltages in the circuit.
  • The participant claims to have derived i1 = 0.09 A and i2 = 0.01 A, along with the corresponding voltages across the resistors.
  • Other participants respond with affirmations of the calculations, indicating that they seem correct.

Areas of Agreement / Disagreement

There appears to be agreement among participants regarding the correctness of the initial calculations, as multiple responses confirm the findings without presenting any counterarguments.

Contextual Notes

No limitations or unresolved issues are noted in the discussion.

Here is the circuit. I have to find the voltage across each resistor and the current i1 and i2.
My attempts are the following:

By KCL,
i2 + i1 = 0.1 A

By KVL,
3 - 5 - 100i1 + 1100i2 = 0

∴ i1 = 0.09 A, i2 = 0.01A
∴ Voltage across 100Ω resistor = 0.09 × 100 = 9 V, voltage across 1100Ω resistor = 0.01 × 1100 = 11 V

Are there any mistakes?
