14.Two resistances of 202in parallel then find their(Rp). (chap 11)& 402 ase connectedequivalent resistance |
|
Answer» The two given resistors be R1 = 20 ohms and R2 = 40 ohms when the resistors are joined in parallel, then the equivalent resistance Rp = 1/ R1 + 1/ R2 = R1 + R2/ R1.R2 = (20 + 40)/20*40 = 60/20*40 = 3/40 ohms R=R1*R2/(R1+R2)=40/3 |
