We need find
Current ( I ) & Potential Difference across 12ohm resistor ( V )
Now, Let's find the current in the circuit
Here,
Potential Difference across the circuit = 2 + 2 + 2
= 6V
Since the resistors are in series
Let's find equivalent resistance
R = R1 + R2 + R3
= 5ohm + 8ohm + 12ohm
R = 25 ohms
By Ohm's law, we get,
V = IR
V/R = I
I = V/R
I = 6/25 A
I = 0.24A
Now let's find the potential difference across 12ohm resistor
In series the current flow will be the same.
So,
I = 6/25A
R = 12ohm
Again by Ohm's law,
V = IR
V = 6/25 * 12
V = 72/25
V = 2.88V
Therefore, the reading shown by
Ammeter is 0.24A
Voltmeter is 2.88V
