Question

3 ohm 5 ohm and 8 ohm resistance are connected in parallel what is the combined resistance​

Answer 1

☆VALID ANSWER☆

Components connected in parallel are connected so the same voltage is applied to each component. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component. In this case, it is a parallel, the voltage across each component will remain the same as 15 V.

Hence, the potential drop across the 6 ohms resistor is 15 V.

Answer 2

Answer :

• The total resistance in the circuit,Rₑ 1.5 Ω.

Explanation :

Given :

• Resistance in the resistor, R₁ = 3 Ω
• Resistance in the resistor, R₂ = 5 Ω
• Resistance in the resistor, R₃ = 8 Ω

To find :

• The equivalent resistance in the circuit, Rₑ = ?

Knowledge required :

• Formula for total resistance in a parallel circuit :

⠀⠀⠀⠀⠀⠀⠀⠀⠀1/Rₑ = 1/R₁ + 1/R₂ + 1/R₃ + ....⠀

[Where, Rₑ, R are the total resistance in the circuit and the resistance in the circuit]

Solution :

By using the formula for total resistance in a parallel circuit and substituting the values in it, we get :

⠀⠀=> 1/Rₑ = 1/R₁ + 1/R₂ + 1/R₃

⠀⠀=> 1/Rₑ = 1/3 + 1/5 + 1/8

⠀⠀=> 1/Rₑ = (40 + 24 + 15)/120

⠀⠀=> 1/Rₑ = 79/120

⠀⠀=> Rₑ = 120/79

⠀⠀=> Rₑ = 1.5 (approx.)

⠀⠀⠀⠀∴ Rₑ = 1.5 Ω

Therefore,

• The total resistance in the circuit is 1.5 Ω.
