Red = 2.
Orange = 3.
Multiplier = 10^3(Orange).
Silver= 10 (Don't Consider Silver because they not given at Maximum Or Minimum Resistance).
Then, 23*10^3.
23000Ohms.
Current = V/R.
= 50/23000
= 0.002173
= 2.17mA Nearly 2.2mA.

Red 2.
Orange 3.
Orange 10^3.
Silver +/- 10%.
23000 +/- 2300.
20700/25300.
Ans is +2.4m.
Orange 3.
Orange 10^3.
Silver +/- 10%.
23000 +/- 2300.
20700/25300.

Use this code:
BBROYGBVGW.
0123456789.
BBROYGBVGW.

Why are we not including tolerance (silver, gold) in our calculations here? Please explain.

V=I*R.
So, given v=50000, R is given as the colour whose R=22727, so we get I=2.2A.

After calculating, I got the value of resistance 25300 max and 20700 min. So which value should I use for resistance- max or min? Please explain me.
