Answer 1

Answer:

The answer to this question is....

Answer 2

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
