UNIT OF ELECTRICAL CURRENT AND CURRENT
MEASUREMENT
The electron is an extremely small unit, and for this reason it is not a
convenient unit to use in the measurement of electric current or of quantity of electricity. The presence of an electric current in a circuit may be detected and its strength may be measured by a number of different methods. Each method is based upon some effect which the current produces under given conditions.
One of these effects is known as electrolytic dissociation. The properties of most conducting liquids are such that when a direct current is maintained in them, the constituent elements of the liquid are separated. For example, when two copper plates are dipped in a solution of copper sulphate and a direct current is maintained in a liquid entering at one plate, the anode, and leaving at the other, the cathode, metallic copper leaves the solution and is deposited on the cathode.

4. Find the wrong statements and correct them:
1. The electron is an extremely big unit.
2. The electron is a convenient unit to use in the measurement of electric
current.
3. The strength of electric current may be measured by several methods.

UNIT OF ELECTRICAL CURRENT AND CURRENT

MEASUREMENT

The electron is an extremely small unit, and for this reason it is not a

convenient unit to use in the measurement of electric current or of quantity of electricity. The presence of an electric current in a circuit may be detected and its strength may be measured by a number of different methods. Each method is based upon some effect which the current produces under given conditions.

One of these effects is known as electrolytic dissociation. The properties of most conducting liquids are such that when a direct current is maintained in them, the constituent elements of the liquid are separated. For example, when two copper plates are dipped in a solution of copper sulphate and a direct current is maintained in a liquid entering at one plate, the anode, and leaving at the other, the cathode, metallic copper leaves the solution and is deposited on the cathode.

3. Find the following equivalents in the text:

1. вимірювання електричного струму the measurement of electric current

2. присутність струму в контурі  The presence of an electric current in a circuit

3. може бути виявлено may be detected

4. рідини,які проводять струм conducting  liquids

5. розчин сульфату меді a solution of copper sulphate

1. The electron is an extremely small unit.

2. The electron is not a convenient unit to use in the measurement of electric

current.

3. The presence  of electric current may be measured by several methods.

4. The properties of most conducting liquids are defined by the separation of the constituent elements of the liquid.​
