Question

(12) A voltmeter of resistance 500 can measure a maximum voltage of 5V. How can it be made to measure a maximum voltage of 100 V?

Answer 1

Answer:

you add a resistor of 500 ohms, you will be able to read 10 Volts actual as 5 volts measured. So to read 100 Volts actual as 5 volts measured, you need to add 10 x this as the total resistance value. So 1,000 x 10 = 10,000 ohms.28-Jun-2020
