Question

Judge the equivalent resistance when 3 ohm and 12 ohm are connected in parallel ​
k

Answer 1

Answer:

the equivalent resistance in parallel is 2.4ohms

Explanation:

we can calculate the equivalent resistance in parallel as 1/Req= 1/R1+1/R2

thus 1/Req = 1/3+1/12

= (4+1)/12

= 5/12

since 1/Req = 5/12

therefore Req= 12/5

=2.4 ohms
