What is the resistance of a 10Base-2 terminating

50 ohms.
52 ohms was also used. I think maybe 50 ohms is a non-standard value for a
resistor, and 52 ohms was available. I only saw one batch of 52 ohms-- the
color stripes said 52 ohms, not just my ohmmeter.
52 OHMS is within 5% of the correct value. If they were 5% resisters,
they would easily be within 10% of 50 ohms. They are probably close
enough to do their job.
This table
50 ohms * 1.10 = 55 ohms for the high +10%
52 ohms * 1.05 = 54.6 ohms for the high +5%
52 ohms * .95 = 49.4 ohms for the low -5%
50 ohms * 0.9 = 45 ohms for the low -10%
shows that a 52 ohm +/-5% is easily within the range of a
+/-10% 50 ohm resister.
