Question

3) Find the resultant resistance in the
following arrangement of resistances.
​

Answer 1

Answer:

R=5.75 ohm

Explanation:

here 5 ohm and 15 ohm are in parallel combination..

then

1/R=1/5+1/15

1/R=4/15

R=15/4

R=3.5 ohm

Again

3.5 ohm and 2.25 ohm are in series combination

then

R=3.5+2.25 ohm

R=5.75 ohm

hope it helps

thank you

plz mark it as branliest

Answer 2

Answer:

answer is 2.51

Explanation:

1/Rp=1/R1+1/R2. 1/5+1/15 lcm 3+1/15 ,,4/15=0.26 + 2.25=2.51 OHM
