Question

when two resistances 1 ohm and 3 ohm are connected in parallel their equivalent resistance is 1 ohm true or false​

Answer 1

Answer:

false

Explanation:

Because R=R1xR2 upon R1+R2

=3x1 upon 3+1

= 3 upon 4 and ans is 4/3ohm

Answer 2

Answer:

false

Explanation:

$R_{1} = 1 ohm \\R_{2} = 3 ohm$

for parallel resistors, the equivalent resistance  1/$R_{p}$ = 1/$R_{1}$ + 1/$R_{2}$

1/$R_{p}$ = 1/1 + 1/3

       = (3+1)/3

       = 4/3 is not equal to 1   therefore the given statement is false
