Question

2. Electrical filaments and elements are usually
made of materials with high resistance to
electricity
3. A solenoid consists of two or more
connected cells.
4. The electric bulb is based on the magnetic
effect of electric current.
5. A doorbell rings because of the
repeated closing and breaking of an
electric circuit​

Answer 1

2)Tungsten is used for making the filaments as it offers high resistance.

3)no the battery consist of two or more connected cells.

4)An electric bulb works on the principle of hearing effect of current. It consists of a tungsten filament with a coating of thorium. This filament gets heated up to emit light when current passes through it.

5)Because of make and break arrangement

Make and break arrangement causes striker to repeatedly hit the metal gong as long as switch is pressed. When Circuit is complete, electromagnet attracts the striker which hits metal gong. As soon as the striker moves, circuit breaks and electromagnet is inactive. Because of flexibility of striker, it moves back to its original position. As soon as it reaches original position, circuit is complete. This process repeats continuously.

Answer 2

As Earth's highest and most massive mountain range, the Himalayas bar the influx of frigid katabatic winds from the icy Tibetan Plateau and northerly Central Asia. Most of North India is thus kept warm or is only mildly chilly or cold during winter; the same thermal dam keeps most regions in India hot in summer.
