Q . there are two resistors connected in parallel. the total resistance has been measured 2 ohm. and one of the resistors is known to be 3 ohm morr than the other. the value odlf small resistor is ................
ReplyDeleteLet the resistances of the resistors be x and x+3.
DeleteTotal resistance = 2 ohm
1/x + 1/(x+3) = ½
Solving this we get x= 3
The value of smaller resistor is 3 ohm
