Question

Three resistor 5Ω,10Ωand15Ω are connected in series and the combination
is connected to a battery of 30 volts. Ammeter and voltmeter are connected. Draw a circuit diagram to connect all the devices in the proper order. What is the readings in ammeter and voltmeter if voltmeter is connected across 10Ω.

Answer 1

Answer:

reading of ammeter is 30ohm .

reading of voltmeter is 10 volts .

Explanation:

total resistance = 5 ohm +10 ohm + 15 ohm = 30 ohm .. ( It was connected in series)

reading of ammeter= 30 ohm .

voltage= 30 volts .

current= voltage/resistance

= 30/30

= 1 ampere

as voltmeter is connected across 10 ohm resistor , voltage across it

= I * R

= 1 * 10

= 10 volts

reading of voltmeter = 10 volts
