Question

. ਸੰਦੀਪ ਨੇ ਬਲਬ ਦੇ ਇਕ ਸਿਰੇ ਨੂੰ ਬੈਟਰੀ ਦੇ ਧਨ ਟਰਮੀਨਲ ਨਾਲ ਤਾਂਬੇ ਦੀ ਤਾਰ ਨਾਲ ਜੋੜਿਆ ਅਤੇ ਬਲਬ ਦੇ ਦੂਸਰੇ ਸਿਰੇ ਨੂੰ ਬੈਟਰੀ ਦੇ ਰਿਣ ਟਰਮੀਨਲ ਨਾਲ ਪਲਾਸਟਿਕ ਦੀ ਤਾਰ ਨਾਲ ਜੋੜਿਆ | ਪਰ ਬਲਬ ਨਹੀਂ ਜਗਿਆ| ਇਸ ਦਾ ਕੀ ਕਾਰਨ ਹੋ ਸਕਦਾ ਹੈ? Sandeep connected one end of bulb to battery's positive terminal with copper wire and negative terminal with plastic wire. But bulb is not glowing. What could be the reason behind this? संदीप ने बल्ब के एक सिरे को बैटरी के धन टर्मिनल के साथ तांबे की तार के साथ जोड़ा और बल्ब के दूसरे सिरे को बैटरी के ऋण टर्मिनल के साथ प्लास्टिक की तार के साथ जोड़ा पर बल्ब नहीं जग रहा इसका क्या कारण हो सकता है? *​

Answer 1

Draw in your notebook the symbols to represent the following components of electrical circuits: connecting wires, switch in the ‘OFF’ position, bulb, cell, switch in the ‘ON’ position, and battery?

Answer:

Connecting wires

Physics Class 7 Electric Currents Connecting Wires

2. Switch in “ON” position

Physics Class 7 Electric Currents Switch ON

3. Electric Bulb

Physics Class 7 Electric Current Bulb

4. Electric Cell

Physics Class 7 Electric Current Electric Cell

5. Switch in “OFF” position

Physics Class 7 ELectric Current Switch OFF

6. Battery

Physics Class 7 Electric Currents Battery

Question2.

Draw the circuit diagram to represent the circuit shown in Fig?

Physics Class 7 Electric Circuits Electric Circuit 5

Answer:

In the above circuit one end of the bulb is connected to the battery and another end to the safety pin.

But the other end of the battery is not connected to the safety pin. Therefore there will be no flow of current as the switch is in “OFF” position.

Answer 2

Answer:

current always flow in copper wire because it good conducter of elecercity ..

according to your question.. he used other wire known plastic wire..plastic wire doesn not conduct electercity ...so when he put a copper wire on both side s of battery then bulb glowingg.....

i hope u can more understand this...
