Question 32
INNAT1 markNeeds review
A linear potentiometer (0 − 10 kΩ) is used to measure the water level as shown in the figure. The resistance between A and C varies linearly from 0 to 10 kΩ for a change in water level from 0 to 20 cm. The sensor is excited using a DC voltage source,
V with an internal resistance,
. If
V, the water level is _____ cm (rounded off to one decimal place).
