Question

If three resistances of 2 ohm, 3 ohm and 4 ohm are connected in parallel, then find the resultant resistance.​

Answer 1

Answer:

• 12/13 ohm is the required resultant resistance.

Explanation:

According to the Question

It is given that

• Resistance,R1 = 2Ω
• Resistance ,R2 = 3Ω
• Resistance ,R3 = 4Ω

All these are connected in parallel .

In parallel combination equivalent resistance is calculated by the sum of reciprocal of resistance of each individual resistors .

• 1/Req = 1/R1 + 1/R2 + 1/R3

substituting the value we get

↠ 1/Req = 1/2 + 1/3 + 1/4

↠ 1/Req = 6+4+3/12

↠ 1/Req = 13/12

↠Req = 12/13 Ω

• Hence, the resultant resistance is 12/13 ohm.
