Question

Redraw the circuit of Question 1. putting in an ammeter to measure
the current through the resistors and a voltmeter to measure the
potential difference across the 12 ohm resistor. What would be the readings
in the ammeter and the voltmeter?​

Answer 1

Answer:

we cannot draw in this app..

Answer 2

Explanation:

Hey mate.....

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

Current flowing through the circuit/resistors = IResistance of the circuit, R = 5 + 8 + 12 = 25Ω

Current flowing through the circuit/resistors = IResistance of the circuit, R = 5 + 8 + 12 = 25ΩI = V/R = 6/25 = 0.24 A

Potential difference across 12 Ω resistor = V1

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

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.

Therefore, the reading of the ammeter will be 0.24 A.The reading of the voltmeter will be 2.88V.
