R1 + R2 of ring circuit

[haptism]

Hi for a ring circuit, is there any need to measure and enter R1 + R2 values on a schedule of results ? Because an r2 value is already measured (together with r1 and rn). If I needed a ring R1 + R2 value to calculate ZS (although i would find ZS with a socket tester so really no need; but if I did) would i find it using the formula ZS = (r1 + r2)/4 ? Thanks all

I remember some idiots in my youth drinking lager & blackcurrant

I also remember going to the pub for the first time with me mates at 14, having a steak and 3 pints of Tartan and threw the lot up. Think it was a bad steak

We just swapped the steak for a few bags of crisps, the ones with a little blue bag of salt in. Obviously not as well off as you Oxford lot. 3 or 4 pints of Home Ales bitter, get into bed and wait for the entire world to start spinning out of control, shortly to be followed by a close quarters encounter with the bog pan. Fantastic, these young un's don't know what they are missing. All at the ripe old age of 14-15 eh??

We just purloined off you posh Notts lads studying at Oxford Unni. Working as a server in the Bursary , saw all sorts from across the UK. Only ever got a free pint from the Scots!
