10) Similarly between dc motor and generator​

Answer 1

9)The LED is connected to the LED chips in a LED lamp. The speciality of this part is that part of the LED that helps in the creation of light.

• LED(Light Emitting Diode)is based on the forward bias where the positive side on the anode is connected to the negative side on the cathode.
• The consumption of power for LEDs are very small as same as its size.
• The applications of LEDs include the backlighting in television, camera flashes and even used to decorate the house by means of LED bulbs.

10) Similarities between dc motor and ac generator are as follows:

• The rotation of a coil in the magnetic field of an electromagnet's pole can be seen both in dc motor and ac generator.
• The transformation of energy can be seen both in dc motor and ac generator.

Correct question: Similarities between dc motor and ac generator
