A) Sinusoid ally
B) Linearly
C) Rectangular
D) Like saw tooth
Correct Answer: D
Solution :
The equivalent circuit similar to that of the standard potentiometer configuration can be drawn as below: Point is at zero potential of point\[Z\]is equal to that of the positive terminal of the battery. As the arm \[PQ\]goes from \[X\]to\[Z\], the potential difference between the point\[R\]and\[S\]goes on decreasing linearly. The potential difference becomes zero when the wiper arm is at point\[Z\]. Then the wiper rotating clockwise comes in contact with point\[X\]. So, the potential difference instantaneously becomes maximum. This repeats itself as shown below: This wave form is like teeth of a hand saw.You need to login to perform this action.
