A 10 V battery is connected to a series combination of two resistances...
The circuit diagram can be represented as follows:
```
___ 4000 Ω ___ 6000 Ω ___
| |
10 V 10,000 Ω
| |
--------------------------
```
From the given information, we can calculate the current flowing through the circuit using Ohm's Law:
V = I * R
Where V is the voltage, I is the current, and R is the resistance.
For the 4000 Ω resistor:
3.226 V = I * 4000 Ω
I = 3.226 V / 4000 Ω
I = 0.0008065 A
Now, let's calculate the voltage across the 6000 Ω resistor using the current calculated above:
V = I * R
V = 0.0008065 A * 6000 Ω
V ≈ 4.839 V
Hence, the value of the voltmeter reading across the 6000 Ω resistor would be approximately 4.839 V.
Therefore, the correct answer is option 'D' (4.838 V).

Therefore, the correct answer is option 'D' (4.838 V).

A 10 V battery is connected to a series combination of two resistances...
Req = 7750 Ω
i = 10/7750
v1 = (10/7750) x 4000 = 5.16
So v2 = 10 – 5.16
v2 = 4.838.
