Why are H-bridge circuits used with DC motors?

A. To reduce motor noise

B. To amplify sensor signals

C. To increase torque automatically

D. To allow bidirectional rotation

Correct Answer is :

D. To allow bidirectional rotation

Explanation

An H-bridge can reverse the polarity applied to a DC motor, allowing its direction of rotation to be reversed.

H-bridge DC motor पर लागू voltage की polarity को reverse कर सकता है। इससे motor को clockwise और anticlockwise दोनों दिशाओं में घुमाया जा सकता है।
