Question

To get 1.5 Ω resistance using only 6 Ω resistors, the number of them required is *t
6 all in parallel
3, all in series
4, all in parallel
2 , in parallel

Answer 1

Answer:

4 all in parallal

Explanation:

equivalent Resistance in parellal when each have equal resistance R= R/n

n= number of resistors

R/n=1.5

6/n= 1.5

n= 6/1.5

n= 4

So 4 resistance in parellal will give required resistance
