Question

I want the answer immediately

Answer 1

Answer:

answer is c

Explanation:

because we know R=V/R

so resistance is inversely proportional to the V

and in the graph R3 resistance has high voltage than others so it has very high resistance

as similar R2 has less voltage than R3and has high. resistance than R1 so answer will be (c)

please follow me

Answer 2

Answer:

R3 > R2 > R1 ( option 3 )

Explanation:

• slope of V-I graph gives resistance
• Slope of I - V graph gives 1/ Resistance or capacitance
• Here I - V graph is given
• So slope give 1 / R
• to fins slope take tan of angle
• as angle increases slope increase
• So when line become steeper , slope increase that is , 1/ R increase that means R decrease
• So least steep line has greatest resistance ( that is 3 rd line R3 ) for I-V graph ( for V - I graph opposite )
