Question

BEFORE YOU START: PLS READ THE FULL QUESTION. IT MIGHT LOOK LONG BUT IT IS EASY. IT MIGHT BE CONFUSING. DONT
SPAM. OR ELSE YOU WILL BE REPORTED. the equivalent resistance of two resistances 1ohm and 10ohm connected in parallel will be less than 1ohm,this is because when a number of resistances are connected in parallel,then their equivalent resistance is less than the smallest individual, so my question is how do you judge the equivalent resistance in series, the one in question is of parallel.

BEST ANSWER WILL BE BRAINLIEST. DONT SPAM!​

Answer 1

here,equivalent resistance in series =1ohm+10ohm

=11ohm

Explanation:

equivalent resistance is the algebraic sum of resistance.

R1+R2=R(in series)

and

(R1×R2)/(R1+R2)=R(in parallel)

Answer 2

Answer:

1 ohm nd 10<ohm are connected in parrallel

there fore their total eqivalent resistance= 1/1+1/10<3=1/r

1001/1000=1/r

r=1000/1001

0.9something is the eqivalent resistance which is less then 1

2question

1ohm nd 1000 ohm nd 1000000 ohm resistance r connected in parallel

therefore their equivalent resistance will v

1/r= 1/1+1/1000+1/1000000=1000000+1000+1/1000000=1001001/1000000

r=1000000/1001001=0.999 ohm

0.999 ohm us the equivalent resistance which is less than 1
