SUMMARY

The discussion centers on calculating electrical parameters for a resistive load rated at 65 W and 110 V when connected to a 230 V, 50 Hz supply. Key calculations include determining the current in the load, the required voltage drop across a series inductor, the inductance of the inductor, and the phase angle of the circuit. Additionally, the advantages of current limitation techniques are explored, with a request for reading materials beyond circuit protection devices like MCBs and fuses.

PREREQUISITES
  • Understanding of electrical circuits and Ohm's Law
  • Knowledge of AC circuit analysis and impedance
  • Familiarity with inductors and their role in electrical circuits
  • Basic concepts of phase angle in AC systems
NEXT STEPS
  • Study AC circuit analysis techniques using resources like Khan Academy
  • Learn about electrical impedance and its calculations
  • Research the principles of inductance and its applications in current limitation
  • Explore practical examples of current limiting devices in electrical engineering
USEFUL FOR

Electrical engineering students, circuit designers, and professionals involved in power systems who seek to deepen their understanding of current limitation techniques and AC circuit behavior.

Hi, I have the following question from an old City & Guilds paper:
A resistive load rated at 65 W, 110 V is to be used on a 230 V, 50 Hz supply.
Calculate
(a) current in the load
(b) voltage drop needed across a pure inductor connected in series with the load
(c) inductance of this inductor
(d) phase angle of the circuit
(e) explain the advantage of this type of current limitation and give one practical example.
Could someone point me to any reading material on this please as I can only find items relating to MCBs and fuses.
Many thanks.
