ELECTRIC CURRENT AND ITS EFFECTS
303397
Working of electric bells is an example of:
1 Mechanical effect of electric current.
2 Heating effect of electric current.
3 Magnetic effect of electric current.
4 None of these.
Explanation:
Magnetic effect of electric current. An electric bell contains an electromagnet, consisting of coils of insulated wire wound round iron rods. When an electric current flows through the coils, the rods become magnetic and attract a piece of iron attached to a clapper. The clapper hits the bell and makes it ring.

What is CFL?
1 Compact Fluorescent Lamp.
2 Compact Fluorescent Lamina.
3 Complete Fluorescent Light.
4 Controlled Fluorescent Light.
Explanation:
Compact Fluorescent Lamp. CFL is Compact Fluorescent Lamp. A compact fluorescent lamp, also called compact fluorescent light, energy - saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent light bulb; some types fit into light fixtures designed for incandescent bulbs.
ELECTRIC CURRENT AND ITS EFFECTS
303399
When a switch is in OFF position. Circuit starting from the positive terminal of the cell stops at the switch. Circuit is open. No current flows through it. Current flows after some time. Choose the combination of correct answer from the following:
1 Only (i) and (ii) are correct.
2 (ii) and (iii) are correct.
3 Only (iv) is correct.
4 All are correct.
Explanation:
(ii) and (iii) are correct. When the switch is off, the circuit is in open position and current does not flow through the circuit as the circuit is not complete. So, the correct options are (ii), (iii).
