Question

D.
Define :
1. Tester
2. Electroplating
3. Electric Current​

Answer 1

Answer:

1. A tester is an item of electrical test equipment used to determine if an electrical path can be established between two points; that is if an electrical circuit can be made. The circuit under test is completely de-energized prior to connecting the apparatus.

2. Electroplating is the coating of an object with a metal. The metal bar dissolves in the solution and plates out on the object, forming a thin but durable coating of metal. It is often used to gold-plate objects for decoration or to stop corrosion.

3. An electric current is a flow of electric charge. Electric charge flows when there is voltage present across a conductor. In electric circuits this charge is often carried by moving electrons in a wire.

Explanation:

Answer 2

1. Tester- A tester is a machine or device that you use to test whether another machine or device is working properly.

2. Electroplating- Electroplating is a process where a coating of metal is added to a conductor using electricity via a reduction reaction.

3. Electric current- An electric current is the rate of flow of electric charge past a point or region.
