Huh? What goes across the spark plug wire is a "spike" or pulse. It has a lot of voltage but the current is quite small. It is certainly not "constant". Because the current is so small, the voltage drop across a resistance wire is negligible. The purpose of the resistance is to increase the time constant of the secondary ignition circuit, which increases the rise time of the spark pulse and reduces the high-frequency harmonics that cause radio static. The only real advantage of solid-core wires is they are more reliable than resistance wires. I've had the same resistance wires on my tractor for over fifteen years and they work just fine.
