Check the attachment for better explanation!!!
Now we can see that,
Both resistors are in series!!
We have,
- Two resistors of 10Ω and 20Ω are in series
- Potential difference = 3 v
- Current = ?
Now we know that,
☛ Rs = R₁ + R₂ + .......... + R(n)
➝ Rs = 10 + 20
➝ Rs = 30Ω
∴ Equivalent resistance of circuit = 30Ω
Now we will use Ohm's law :
☛ V = I * R
➝ 3 = I * 30
➝ I = 3/30
➝ I = 0.1 A
∴ Current flowing in circuit = 0.1 A

Now in the second part :
- Resistance (R) = 10Ω
- Current (I) = 0.1 A
- Potential difference (V) = ?
Again using Ohm's law :
☛ V = I * R
➝ V = 0.1 × 10
➝ V = 1 v
∴ Potential difference across 10Ω resistor = 1 volt
