Question

भूमिगत तना में उपस्थित होता है​

Answer 1

Eight different resistors of 1Ω, 2Ω, ... , 8Ω are connected in parallel across a battery of 10V.

We have to find current flow in 1Ω resistor.

\star⋆ We know that, potential difference across each resistor remains same in parallel connection.

Therefore potential difference across all eight resistors will be 10V.

We have asked to find current flow in 1Ω resistor.

\star⋆ As per ohm's law, current flow in resistor is directly proportional to the applied potential difference. (at constant temperature)

V = IR

V denotes voltage of battery

I denotes current

R denotes resistance

By substituting the values,

➝ V = I × R

➝ 10 = I × 1

➝ I = 10/1

➝ I = 10A

∴ 10A current will flow in resistor of 1Ω.

Answer 2

Answer:

भूमिगत तना (Underground stem): पौधे के तने का वह भाग जो भूमि के अंदर पाया जाता है, भूमिगत तना कहलाता है। भूमिगत तने में पर्व सन्धियाँ, पर्ण कलिकाएँ तथा शल्क पत्र पाये जाते हैं। प्रतिकूल परिस्थितियों में भूमिगत तने भोजन संग्रह करने के कारण मोटा एवं मांसल हो जाता है।
