Question

high voltage is dropped
across ? (100 ohm/200 ohm )

more heat will be generated in? (100 ohm/200 ohm)

identify the resistor through which large current passes?

If potential difference between 100 ohm is 10v ,how much work is done by the battery to move one coulomb charge from A to B ?

I mark as brainlist answer

Answer 1

Answer

1. 200 ohm
2. if current is same then 200 ohm is answer.
3. 100 ohm
4. Work done W= q×V, or W= 1×10=10 joules.

Explanation:

since V=IR so,

1. if current is same in both resistance, higher the resistance higher is potential drop.
2. Heat is directly proportional to resistance so higher the resistance higher is heat.
3. as current is inversely proportional to resistance so higher the resistance lower is current.
4. work done in moving small charge dq from A to B is, dW=dq×V.
