Question

find the equivalent resistance between X and Y​

Answer 1

Answer:

since by the figure

resistor of (3 ohm,7 ohm) and 10 ohm are in parallel

Explanation:

so the equivalent resistance

=1/7+3 + 1/10

= 1/10 + 1/10

= 2/10

= 5 ohm

now let this resistance be a single one

let this R

after that

R and 7ohm, 3 ohm resistor are in series

so the required equivalent resistance =

=7+3+5

15 ohm

hope u understand

Answer 2

Explanation:

ohm resistor= 5 no. of 20 ohm resistors in parallel.

5 ohm resistor= 4 no. of 20 ohm resistors in parallel.

So as a total 5+4+1 =10 no.s of 20 ohm resistors in parallel.

Equivalent resistance= 20/10 ohm =2 ohm.

I know it is kind of
