Question

3 resistors 10, 20,30 are connected in parallel • find out the resulant and r esistancë in circuit​

Answer 1

Given

• Three resistors of resistance 10Ω, 20Ω & 30Ω are connected parallely

To Find

• Equivalent resistance

Solution

☯ The equivalent resistance of a parallel combination is given by, 1/R = 1/R₁ + 1/R₂ ... + 1/Rₙ

━━━━━━━━━━━━━━━━━━━━━━━━━

✭ According to the Question :

⇒ 1/R = 1/R₁ + 1/R₂ ... + 1/Rₙ

⇒ 1/R = 1/10 + 1/20 + 1/30

⇒ 1/R = 6/60 + 3/60 + 2/60

⇒ 1/R = (6+3+2)/60

⇒ 1/R = 11/60

⇒ R = 5.45Ω

Answer 2

Given

3 resistors 10, 20,30 are connected in parallel • find out the resulant and r esistancë in circuit

To find

• Equivalent resistance

Solution

According to the question

1/R = 1/R_1 + 1/R_2...+1/R_n

1/R = 1/10 + 1/20 + 1/30

1/R = 6/60 + 3/60 + 2/60

1/R = (6+3+2)60

1/R = 11/60

R = 0.18Ω
