Answer 3: conventional current and electronic current: When a conductor AB is connected across the terminals of a cell , free electrons begin to drift or move from its end B connected to the negative terminal of the cell to the end A connected to the positive terminal of the cell.

The current constituted by flowing electrons is called electronic current.

Clearly, the direction of electronic current is from negative terminal to positive terminal. By convention, the direction of motion of positive charges is taken as the direction of electric current. It is from positive terminal to negative terminal.

As the electrons are negatively charged, the direction of conventional current is an electric circuit is taken as opposite to the direction of the flow of electrons.

Question 4: What is meant by potential difference between two points?

Answer 1: This law states that the current I flowing through a conductor is directly proportional to the potential difference V applied across its ends, provided the temperature and other physical condition remain unchanged. Question 2: What is an ammeter? How is it connected in a circuit?

An ammeter is always connected in series in a circuit, so that entire current, which we wish to measure, flows through it. Question 3: What is meant by resistance of a conductor? Answer 3: Resistance: The resistance of a conductor is its property by virtue of which it opposes the flow of current through it.

It is equal to the ratio of the potential difference applied across the conductor to the current flowing through it. Circles consists of tangent of a circle at point of contact. There are two theorems which will be asked for proof.

Theorem 1: The tangent at any point of a circle is perpendicular to the radius through the point of contact. Theorem 2: The lengths of tangents drawn from an external point to a circle are equal.

Constructions gives an idea of dividing a line segment into given ratio, tangents to a circle from a point outside it and construction of a triangle similar to a given triangle. Steps of constructions must be written in order to understand easily. Areas related to circles suggest the methods to find area of sectors, segments, area and perimeter of plane figure triangles, simple quadrilateral and circles. Questions based on sectors or segments are restricted to central angles 60, 90, etc.
