Question

why it is difficult to measure the rate of change of current

Answer 1

Answer:

Current is sometimes a little harder tomeasure than voltage because an ammeter usually needs to be inserted into a break in the line carrying the current rather than just connected across two points in a circuit as done for voltage.

Answer 2

Answer: It is due to the resistance offered by the conductor during the flow of current. So, exact reading of ammeter cannot be taken which makes difficult to measure the rate of change of current.

Explanation:

• Yes it is true that we can't measure the exact value of current.
• It is due to the resistance offered by the conductor during the flow of current.
• The resistance is due to the collision of the charges within the conductor.
• Hence, it is difficult to get the exact value of current using ammeter it keeps on fluctuating so rate of change of current becomes difficult to measure.
