It is the reason something exist for example if you ask what the purpose of a car is you would say its purpose is to get me from one place to another.
Intelligent, Wasn't that bright is sarcasm, like, Wow that was smart (aka stupid)

Roald Dahl uses dramatic irony(a case when the reader knows something the characters don't) in “Lamb to the Slaughter” to develop a feeling of suspense in the reader, leaving them wanting more.

The impedance of transformer coil that has 600 feet is 10+j 22.62 Ω (ohms)
Explanation:
It is given that
a #22 copper wire has resistance= R= 10 Ω
inductance= I=0.06 H
N=60 HZ
X= 2π * N * I
=2 * 3.14 * 60 *0.06
X=22.62 Ω
Impedance is calculated by
Z = R + j * X
=10+ j (22.62 Ω)
Z= 10+ j 22.62 Ω
The impedance of a transformer coil that has 600 feet is Z= 10+ j 22.62 Ω
