Question

find the resistance effective from pq​

Answer 1

Answer:

1.2ohm

Explanation:

4 ohm and 6ohm are connected in series therefore R1+R2=4+6=10ohm

similarly,3ohm and 7ohm are connected in series therefore R1+ R2=7+3=10ohm

and the three are now connected in parallel

therefore 1/R1+1/R2+1/R3=1/10+1/10+1/1,

1/5+1=5+1/5=6/5=1.2ohm

(After finding two in series parallel diagram is shown in picture)

Hope it helps..........

Answer 2

Answer:

10 /12

Explanation:

6 ohm and 4ohm are in series

so their equivalent resistance is 10ohm .

now , 10 ohm and 1ohm are in parllel.

so their equivalent resistance is 10 / 11 ohm .

7 and 3 ohm are in series. so their equivalent resistance is 10 ohm

finally 10 / 11 ohm & 10 ohm are in parllel.

so answer is 11 / 10 +1/10 .

1/R = 12/10

R = 10 /12
