1.Differentiate between Alternating current and Direct current. [simple words]
2. What is an Electric cell ?
Answers
Answer:
1. Direct current (DC) is the flow of electric charge in only one direction. ... Alternating current (AC) is the flow of electric charge that periodically reverses direction. If the source varies periodically, particularly sinusoidally, the circuit is known as an alternating current circuit.
2. An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or using electrical energy to cause chemical reactions.

Answer:
1)Electrons only move in a forward direction in a DC motor. The frequency of the alternating current is generally in between 50 to 60 Hz. There is a change in the direction of the current electricity flow due to the rotating magnets. The direct current flows in a single direction due to steady magnetism.

Direct current (DC) is the flow of electric charge in only one direction. Alternating current (AC) is the flow of electric charge that periodically reverses direction. If the source varies periodically, particularly sinusoidally, the circuit is known as an alternating current circuit.
2)Cell, in electricity, unit structure used to generate an electrical current by some means other than the motion of a conductor in a magnetic field. A primary, or voltaic, cell produces electricity by means of a chemical reaction but is not rechargeable to any great extent.
