Question

(Β)
10. A wire that has resistance R is cut into two equal pieces. The two parts are joined in parallel. What is the
resistance of the combination ?
Il Calculate the combined resistance in each case :
2Ω
500Ω
4 Ω
3 Ω
4 Ω
2Ω
(c)
(0)​

Answer 1

Answer:

if wire has res 4, then when cut into 2 pieces, each will have res 2 ohm

when they are put in parallel total res will be

1/(1/2 + 1/2) = 1/1 = 1

similarly you can do the rest
