A spring controlled moving iron voltmeter draws a current of 1 mA for ...
Given Data:
Current for full scale value = 1 mA
Full scale value = 100 V
Calculating Meter Reading:
Given that the current drawn by the moving iron voltmeter is directly proportional to the voltage being measured. Therefore, we can use the concept of proportionality to calculate the meter reading for a current of 0.5 mA.
- For a current of 1 mA, the meter reads 100 V (full scale value)
- For a current of 0.5 mA, the meter reading can be calculated as follows:
Using the formula:
Current1 / Reading1 = Current2 / Reading2
Substitute the values:
1 mA / 100 V = 0.5 mA / Reading2
Solving for Reading2:
Reading2 = (0.5 mA / 1 mA) * 100 V
Reading2 = 50 V
Therefore, when the meter draws a current of 0.5 mA, the meter reading is 50 V.
Answer:
Therefore, the correct answer is option 'A) 25 V'.
Current for full scale value = 1 mA
Full scale value = 100 V
Calculating Meter Reading:
Given that the current drawn by the moving iron voltmeter is directly proportional to the voltage being measured. Therefore, we can use the concept of proportionality to calculate the meter reading for a current of 0.5 mA.
- For a current of 1 mA, the meter reads 100 V (full scale value)
- For a current of 0.5 mA, the meter reading can be calculated as follows:
Using the formula:
Current1 / Reading1 = Current2 / Reading2
Substitute the values:
1 mA / 100 V = 0.5 mA / Reading2
Solving for Reading2:
Reading2 = (0.5 mA / 1 mA) * 100 V
Reading2 = 50 V
Therefore, when the meter draws a current of 0.5 mA, the meter reading is 50 V.
Answer:
Therefore, the correct answer is option 'A) 25 V'.
