Question

How does a fan use electrical energy? (a) The fan turns electrical energy into energy of motion. (b) The fan turns wind energy into electrical energy. (c) The blades of the fan spin and produce electrical energy. (d) The fan turns electrical energy into light and heat energy.

Answer 1

Answer:

Option (a) The fan turns electrical energy into energy of motion.

Explanation:

A fan is a device which operates on electric current. It receives electrical energy and transform it to rotational motion(i.e motion about a fixed point)

Answer 2

Answer:

A). The fan turn electrical energy into energy of motion.

Explanation:

When electrical energy is applied to fan, it moves through its coils and then rotors which turns the blade of the fan. The rotors and the coil converts the electrical energy into energy of motion through centripetal force. While the blades of the fan remains in constant centripetal acceleration, the fan continues to circulate the air around.
