Question

please answer this question

Answer 1

Total resistance =1/10+1/5+1/15
=11/30

Answer 2

hi mate,

there are 3 resistors which are connected in parallel, and we need to find the total resistance.


therefore,. the total resistance in parallel is =

1/R= 1/R1 + 1/R2 + 1/R3


$\frac{1}{r} = \frac{1}{10} + \frac{1}{5} + \frac{1}{15}$



$= \: \frac{5 + 10}{50} + \frac{1}{15}$



$= \: \frac{15}{50} + \frac{1}{15}$


$= \: \frac{3}{10} + \frac{1}{15}$


$= \: \frac{45 + 10}{150}$


$= \: \frac{55}{150}$


$= > \: \frac{11}{30} = 0.36ohm$



hope this helps you
