In summary, the conversation is about calculating the current, voltage drop, inductance, and phase angle of a circuit using a resistive load and a pure inductor. The person is also looking for reading material on this topic, specifically related to MCBs and fuses. The discussion also mentions the potential advantage of using this type of current limitation, with a practical example. The City & Guilds paper is likely a test or exam for a course or certification.

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.
