Current Electricity Charging Discharging Of Capacitors Question 199
Question: The potential gradient along the length of a uniform wire is $ 10,volt/metre $ . $ B $ and $ C $ are the two points at $ 30,cm $ and $ 60,cm $ point on a meter scale fitted along the wire. The potential difference between $ B $ and $ C $ will be
[CPMT 1986]
Options:
A) $ 3,volt $
B) $ 0.4,volt $
C) $ 7,volt $
D) $ 4,volt $
Show Answer
Answer:
Correct Answer: A
Solution:
Potential gradient = Change in voltage per unit length \ $ 10=\frac{V _{2}-V _{1}}{30/100}\Rightarrow V _{2}-V _{1}=3,volt $
