Click For Summary
The discussion revolves around a question from an old City & Guilds paper regarding a resistive load rated at 65 W and 110 V, intended for use on a 230 V supply. Participants seek assistance in calculating the current in the load, the necessary voltage drop across a series inductor, the inductor's inductance, and the circuit's phase angle. Additionally, they inquire about the advantages of current limitation and practical examples. There is a request for reading materials related to this topic, as existing resources primarily focus on MCBs and fuses. The conversation highlights the need for educational resources on electrical impedance and AC circuit analysis.

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.

Thread 'RF magnetic field generation'

Hello! I want to generate an RF magnetic field at variable frequencies (from 1 to 20 MHz) using this amplifier: https://www.minicircuits.com/WebStore/dashboard.html?model=LZY-22%2B, by passing current through a loop of current (assume the inductive resistance is negligible). How should I proceed in practice? Can i directly connect the loop to the RF amplifier? Should I add a 50 Ohm in series? Thank you!
