Question

what is the equivalent resistance of conductor of 5 ohm and 10 ohm in parallel​

Answer 1

Answer:

the 5 and 10 ohm resistors in series give you a 15 ohm equivalent resistance in parallel with two 5 ohm resistors. The Requiv. is 1 / (1/5 + 1/5 + 1/15) = 1 / (3/15 + 3/15 + 1/15) = 1 /(7/15) = 2.14 ohms more or less

Answer 2

so when we have only two parallel resistors

we apply this formula =Req=R1×R2/R1+R2
