Question

Redraw the circuit of question 1, putting in an ammeter to measure the current through

the resistors and a voltmeter to measure potential difference across the 12 Ω resistor.

What would be the readings in the ammeter and the voltmeter?​

Answer 2

Answer:

An ammeter should be connected in the circuit in series with the resistors. To measure the potential difference across the resistor it should be connected in parallel, as shown in the following figure

The resistances are connected in series.

Ohm’s law can be used to obtain the readings of ammeter and voltmeter. According to Ohm’s law,

V = IR,

Where,

Potential difference, V = 6 V

Current flowing through the circuit/resistors = I

Resistance of the circuit, R = 5 + 8 + 12 = 25ohm

I = V/R = 6/25 = 0.24 A

Potential difference across 12ohm resistor = V1

Current flowing through the 12ohm resistor, I = 0.24 A

Therefore, using Ohm’s law, we obtain

V1 = IR = 0.24 x 12 = 2.88 V

Therefore, the reading of the ammeter will be 0.24 A.

The reading of the voltmeter will be 2.88 V.
