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 \underline{\boxed{\orange{4.2Ω}}}
