Question

How many resistances are used in a Wheatstone bridge?

✓

Answer

4

Explanation:
Wheatstone bridge is an arrangement of four resistors P, Q, R, and S, such that if we know the value of the resistances of any three of them, we can obtain the value of fourth unknown resistance. Therefore, there are 4 resistances in a Wheatstone bridge.
