Ammeter has 10 divisions between 0 to 0.5A
So, reading of one division
{ it is also known as least count }

= {gap between higher value and lower value }/number of divisions

= (0.5A - 0)/10 = 0.05A

∴ reading of one division = 0.05A
∴ reading of 17 division
= 17 × reading of one division
= 17 × 0.05 = 0.85A

Hence, the value corresponding to 17 divisions= 0.85A

That's all🙂

Calculating the Value Corresponding to 17 Divisions on the Ammeter

To calculate the value corresponding to 17 divisions on the ammeter, we need to determine the value represented by each division and then multiply it by the number of divisions.

Step 1: Determine the Value of Each Division

We are given that the ammeter has 10 divisions between 0 and 0.5A. Therefore, we can calculate the value of each division by dividing the total range (0.5A) by the number of divisions (10):

Value per division = Total range / Number of divisions
= 0.5A / 10
= 0.05A

Hence, each division on the ammeter represents a value of 0.05A.

Step 2: Calculate the Value of 17 Divisions

Now that we know the value per division, we can calculate the value corresponding to 17 divisions by multiplying the value per division by the number of divisions:

Value of 17 divisions = Value per division * Number of divisions
= 0.05A * 17
= 0.85A

Therefore, the value corresponding to 17 divisions on the ammeter is 0.85A.

Explanation:

The ammeter is a device used to measure electric current. It consists of a calibrated scale with divisions that indicate the magnitude of the current flowing through it. In this case, the ammeter has 10 divisions between 0 and 0.5A, which means that each division represents a value of 0.05A.

During the experiment to verify Ohm's law, the student observes that the needle on the ammeter indicates 17 divisions. To determine the corresponding value, we multiply the value per division (0.05A) by the number of divisions (17). This calculation gives us a value of 0.85A.

Therefore, when the needle of the ammeter indicates 17 divisions, the current flowing through the circuit is 0.85A. This value can be used to analyze the relationship between voltage, current, and resistance in accordance with Ohm's law.
