Question

three resistance Rohm,8ohm and 12 ohm connected in a series in a circuit if the resultant resistance in the circiut of 20ohm find the value of R,1​

Answer 1

CAN ANYONE TELL ME WHATS RUDE IN THAT.. HUHH..

ANYWAYS ANS IS IN THE ATTACHMENT

Answer 2

Answer:

R1= 0 ohm

Explanation:

Given-R2=8 ohm

R3=12 ohm

R.R=20 ohm

Now by formula of equivalent resistance of series combination of resistors

R.R=R1+R2+R3

20=R1+8+12

20=R1+20

20-20=R1

R1=0 ohm
