Question # 1

Define resistivity and electrolysis.

Ans 1: The resistance of a meter cube of a material is called resistivity.Certain liquids such dilute sulphuric acid or copper sulphate solution conduct electricity due to some chemical reactions that take place within them.The study of this process is known as electrolysis.

Question # 2

What is meant by tolerance?

Ans 1: Tolerance means the possible variation from the marked value.

Question # 3

Write about any two sources of Current.

Ans 1:
1. Electric generators convert mechanical energy into the electrical energy.
2. Solar cells convert sunlight directly into electrical energy.
3. Thermocouples convert heat energy into electrical energy.

Question # 4

State Ohm's law and write its formula.

Ans 1: It states that "the current flowing through a conductor is directly proportional to the applied potential difference provided that the physical state remains same"
V=IR
Resistance: The opposition against the flow of current is known as resistance.The SI unit of resistance is Ohm
R=V/I

Question # 5

Do two long and parallel current carrying wires attract each other?

Ans 1: Yes ,If the direction of current is same in two long parallel current carrying wires.Because the opposite pole of electromagnet comes in front of each other and attracts.

Question # 6

State Ohm's law and basic principle of electroplating.

Ans 1: Current passing through a wire is directly proportional to the potential difference applied across its ends provided that the physical state conductors remains same.
Basic principle of electroplating is a process of coating a thin layer of sum expensive metal of (gold,silver etc) on a article of some cheap metal.

Question # 7

What does the equation H=I²Rt show?

Ans 1: This equation show the heating effect,During their motion free electrons collide frequently with the atom of metal.on each collision they transfer some of their kinetic energy to the atom with which they collide.And these collisions produce heating effect in the wire.

Question # 8

What is meant by tolerance of resistors?

Ans 1: Tolerance is the measure of possible variation from the marked value,A gold band has +-5% tolerance ,silver has +-10% and no band at all wounf mean a +-20 tolerance.

Question # 9

How can rheostat be used as potential divider?

Ans 1: By adjusting the sliding contact resistance of the rheostat can be altered which in turn would regulate the potential offered by the cell E to the main circuit,And thus a rheostat can be used as potential divider.

Question # 4

Why potential meter is accurate measuring meter?

Ans 1: The voltage measured using potentiometer is the voltage across the terminal of the cell when current is not following through it.This voltage is exactly the emf of the cell.Further the accuracy of a potentiometer can be increased to a great extent by increasing the length of the "potentiometer wire".

Question # 5

Define resistivity and electrolysis.

Ans 1: The resistance of a meter cube of a material is called resistivity.Certain liquids such dilute sulphuric acid or copper sulphate solution conduct electricity due to some chemical reactions that take place within them.The study of this process is known as electrolysis.

Question # 7

Why does no current pass through Galvanometer in a balanced wheat stone bridge although the keys in the circuit are closed ?

Ans 1: No current pass through the galvanometer when wheat stone bridge is balanced.Because at this stage ,both the terminals of the galvanometer are at the same potential.Hence no current will flow through it.

Question # 8

Name any four source of current.

Ans 1: Source of current are
1. Cells
2. Electric generators
3. Thermocouples
4. Solar cells

Question # 9

Question # 10

What is short circuit and open circuit mean to you?

Ans 1: when switched is close and current is passing through the circuit,It is called closed circuit and in this situation resistance is zero whereas the circuit is said to be open if it has infinite resistance and no current is passing through it.
