Series Circuit Resistor Help: Solutions for Q1 and Q2

Click For Summary
SUMMARY

This discussion focuses on solving voltage readings in series and parallel resistor circuits, specifically addressing two homework questions (Q1 and Q2). The participants clarify that in parallel circuits, resistors share the same voltage, while in series circuits, the total voltage is divided among the resistors based on their resistance values. The fundamental equation used is V=IR, which is essential for calculating voltage drops across resistors. The correct application of Kirchhoff's Second Law is emphasized, stating that the sum of the voltage drops in a closed loop equals the total voltage supplied.

PREREQUISITES
  • Understanding of Ohm's Law (V=IR)
  • Knowledge of series and parallel resistor configurations
  • Familiarity with Kirchhoff's Voltage Law
  • Basic circuit analysis skills
NEXT STEPS
  • Study the principles of series and parallel circuits in depth
  • Learn how to apply Kirchhoff's Laws in circuit analysis
  • Practice calculating voltage drops using Ohm's Law with various resistor values
  • Explore advanced circuit analysis techniques, such as Thevenin's and Norton's theorems
USEFUL FOR

Students studying electrical engineering, educators teaching circuit analysis, and anyone seeking to improve their understanding of resistor networks and voltage calculations.

Right ok, all the question says is:

"For each of the following circuits complete the readings of the voltmeters."

If it's any help, it's related to Kirchoff's Second Law that in any closed loop, the sum of the p.d. across components in the loop is equal to the p.d. of the power supply.

Sigh.

Well, that's a completely different question then. The resistor values can be anything.

To fill in the blank voltmeter readings, you just remember that the voltage across parallel components is always the same, and like you said, the sum of the voltage drops and increases around a closed loop has to add to zero. You should be able to fill in the blank voltmeters now.
