7. the voltage difference between the outputs of an unbalanced bridge circuit is \n a zero \n b a positive value \n c a negative value \n d a positive or negative value

Answer

Brief Explanations:

In an unbalanced bridge - circuit, the voltage difference between the outputs can be either positive or negative depending on the nature of the imbalance. For example, if resistances are unbalanced in a Wheatstone - bridge, the potential at one output can be higher or lower than the other.

Answer:

D. a positive or negative value
