Answer
- Equivalent resistance is 4.2Ω
Explanation
Given
- There are two resistors of 2Ω and 3Ω connected in parallel
- These two are connected in series with a resistor of 3Ω
To Find
- The equivalent resistance?
Solution
So we know that parallel connection is given by,
➝ 1/R = 1/R¹+1/R².....
➝ 1/R = 1/2 + 1/3
➝ 1/R = {1/2× 3/3} + {1/3 A× 2/2}
➝ 1/R = 3/6 + 2/6
➝ 1/R = 5/6
➝ R = 6/5
➝ R = 1.2 Ω
So then they are connected in series with the 3Ω resistor
➝ R = R¹+R²....
➝ R = 3+1.2
➝ Equivalent Resistance = 4.2Ω

Given
- Two resisters of 2Ω and 3Ω are connected in parallel and these two are connected in series with a resistor of 3Ω.
To find
- Equivalent resistance.
Solution
★ In parallel connection
→ 1/R = 1/R¹ + 1/R²
→1/R = 1/2 + 1/3
→ 1/R = 5/6
→ R = 6/5
→ R = 1.2Ω
★ In series connection
→ R = R¹ + R²
→ R = 3 + 1.2
→ R = 4.2Ω
Hence,
The equivalent resistance is
