Testing & TroubleshootingQuestion 492 of 521
Two 20 ohm resistors are connected in parallel. What total resistance will an ohmmeter read?
a.10 ohms
b.40 ohms
c.20 ohms
d.400 ohms
Explanation
For two equal parallel resistors, the total is half of one: 20 ohms / 2 = 10 ohms. Option b is the series total, c is a single resistor, and d multiplies them.
