Question
![A rectangular copper block is depth \( d \) along \( z \), width \( w \) along \( y \), and length \( l \) along \( x \). In response to a wave incident upon the block from above, a current is induced in the block in the positive \( x \)-direction. Determine the ratio of the AC resistance of the block to its DC resistance at frequency \( f \).
\[
\sigma = 5.8 \times 10^7 \, \frac{S}{m}
\]
\[
l = 1.2 \, m \quad d = 40 \, cm \quad w = 50 \, cm \quad f = 2 \, kHz
