Thanks, Al. I won't claim to fully understand it (yet) but now have a better idea. I've got 'Foundations of Wireless' so will have another go at reading that.
I know maths is usually used to explain things but it's just something I can't seem to grasp: V=IR is meaningless but tell me that the greater the current flowing through a resistance the bigger the potential across it will be and I understand.
Even going back to school we'd be set questions like "If your are filling a fifty gallon bath and the tap is delivering five gallons a minute but the bath is leaking two gallons a minute how long would it take to fill?" any my immediate thought would be "Fix the leak" followed by "Use a stop-watch."
I like to think I'm improving; just saying that it isn't something I find at all easy.
By the way, I got a CSE Grade 2.
