A wire has a resistance of 6 . It is cut into two parts and both half values are connected in parallel. The new resistance is

Step-by-step solution

Given, resistance of the wire, R=6 When it is cut in two equal parts, then resistance of the cach part of wire is given by r= R 2 =3 ( R l ) Now, these new resistances are connected in parallel wmbination. The equivalent resistance is given bÿ aligned 1 R_ eq &= 1 r + 1 r 1 R_ eq &= 1 3 + 1 3 = 2 3 R_ eq &=1.5 aligned
