Or can stranded wire of the same gauge be subsitituted for solid wire without any consequences? The reason I ask is because its for a massive 4kJ capacitor discharge circuit, and I need all the energy delivered to the power coils im using, cant afford to have much leakage inductance.
Stranded wires have slightly higher inductance than solid wires, but this is noticable only on transmission lines and larger conductors. if you are only using a short conductor, i don't think the inductance of the wire will affect the system, unless the wire is coiled.
You question about Inductance seems illogical. I can't imagine how a straight wire will affect a sudden discharge of current unless the wire is coiled (inductor) or have a shield attached to ground(capacitor). I believe the difference between the two wires are their direct current resistance which is very negligible if the wires are just a few feet long. The Capacitor that will discharge current directly to a coil is a 'tank circuit' and is a type of oscillator. Most likely, The inductance you will experience is caused by the power coil itself that feeds it back to the capacitor and vise versa. If that is true, I recommend a reverse shunt diode across the coil and a series diode between the capacitor and the coil.
