Guys what did you write for the fuse question and the other one regarding the placement of a fuse or a circuit breaker?
For fuse I chose 1A ... not so sure and for the other question I chose the position of both the fuse and the circuit breaker at X (live wire)... am I correct
The echo for the click was the ZY position (not sure of the abbriviations) but it was the one with the short distant wall.
For the copper&wood question... I didn't choose copper at all because it's a good conductor of heat and the whole thing will be really hot .. so it was obviously the other end of the wood?
for the echo thing im 100% sure it was zy because it was a repeated question i saw the answer in the marking scheme
Yes it was repeated actually
