f a box form of bridge range from 1 to10,000 ohms, and the ratio coils are 1, 10, 100, and 1000 ohms, whatratio would you use to measure 1,000,000 ohms? 6. If the same box used in problem 5 were used to measure anunknown resistance of 0.01 ohms, what must be the ratio ? 136.

These tests are called the loop tests, because the faulty wireis always connected at its distant end with a good wire and thetwo in combination make a loop. The loop is…
