Question

4. Four resistances of 16 ohms each are connected in parallel Four such combinations are connected in series.
What is the total resistance ?

​

Answer 1

Explanation:

in parallel Effective Resistance is-R1×R2/R1+R2

but here same resistors are connected so ressistance of a ressistor/no.of ressistors (n/r)

so. 16/4=4ohm

in series connection R1+R2+R3..

SO,. 16+16+16+16=64ohm
