Match the column ‘A’ with column ‘B’.

Differentiate between conductors and insulators.

State Fleming’s Right Hand Rule.

Answer the following:

State the principles of the electric motor and electric generator. 

Name any six domestic appliances based on the heating effect of electric current.

Rewrite the following statement by selecting the correct option:

1 A = ____________ mA.

Explain ‘Electric generator’ with the help of the following points:

1. Diagram of an AC Generator with labelling
2. Principle of an electric generator
3. The function of slip rings
4. Any two uses of a generator.

Answer the following question:
what is the heating effect of the electric current? state any four applications of it?

Answer the following question:
State the effect on the magnetic needle in Oersted’s experiment when:  
(a) the current is passed through the wire.  
(b) the current through the wire is increased
(c) the current through the wire is reversed. 

Choose the correct option:

A conductor rod of length (l) is moving with velocity (v) in a direction normal to a uniform magnetic field (B). What will be the magnitude of induced emf produced between the ends of the moving conductor?

Observe the given figure of Fleming’s Right Hand Rule and write the labels of A and B correctly.

Read the given passage and answer the following questions:

The home electrical connection consists of ‘live’, ‘neutral’ and ‘earth’ wires. The ‘live’ and the ‘neutral’ wires have potential difference of 220 V. The ‘earth’ is connected to ground. Due to a fault in the equipment or if the plastic coating on the ‘live’ and the ‘neutral’ wires gives a way the two wires come in contact with each other and a large current flows through it producing heat. If any inflammable material (such as wood, cloth, plastic, etc.) exists around that place it can catch fire. Therefore a fuse wire is used as a precautionary measure.

1. Name the two wires having potential difference of 220 V.
2. What is a short circuit?
3. Write the function of a fuse.

The unit of electrical power is _______.

The right-hand thumb rule is also called _______ rule.

Which of the following scientist invented the rule of electromagnetic induction?

Alternating current : oscillatory :: Direct current : _______

Write two devices based on the heating effect of electric current.

Match the columns.

Explain the importance/uses of fuse wire.
