Question

For a potentiometer, the potential gradient is given as 0.1 V/cm . The same potential gradient in V/m will be _____ 
A. Constant velocity
B. Constant acceleration
C. Constant kinetic energy
D. Constant displacement​

Answer 1

Answer:

Explanation:

R=  

1

v

​

=  

0.1

1

​

=10

p.d across R in series with x=0.025×100

=2.5v

P.d across ×=(p.d across both-pd across R)

P.d across ×=(2.5−1.0)=1.5

current ×=0.1A

So x=  

1

v

​

=  

0.1

1.5

​

=15
