Question

Jumpering out the resistors in a resistance-controlled three-speed fan will cause the motor to

a. run at highest speed.
c. run at lowest speed.
b. run at medium speed.
d. stop immediately

Answer 1

The answer to the question stated above is letter a. run at highest speed.

Jumpering out the resistors in a resistance-controlled three-speed fan will cause the motor to run at highest speed. If resistors are jumpered, the three-speed fan will over speed and probably burns out.
