1.	Find the equivalent resistance when 5 Ω, 10 Ω, and 30 Ω resistors are connected in parallel
Answer» Answer: effective resistance is 3 Ω Step-by-step explanation: Let R1 = 5 Ω , R2 =10 Ω, R3 = 30 Ω For parallel combination, effective resistance RP is 1/ Rp = 1/R1 + 1/R2 + 1/R3 1/Rp = 1/ 5 + 1/10 + 1/ 30 = ( 6 + 3 + 1) / 30 = 10/ 30 = 1/3 Rp = 3 Ω Hence, effective resistance is 3 Ω

Find the equivalent resistance when 5 Ω, 10 Ω, and 30 Ω resistors are connected in parallel

Answer»

Answer:

effective resistance is 3 Ω

Step-by-step explanation:

Let R1 = 5 Ω , R2 =10 Ω, R3 = 30 Ω

For parallel combination, effective resistance RP is

1/ Rp = 1/R1 + 1/R2 + 1/R3

1/Rp = 1/ 5 + 1/10 + 1/ 30 = ( 6 + 3 + 1) / 30 = 10/ 30 = 1/3

Rp = 3 Ω

Hence, effective resistance is 3 Ω
