# Predicting current flow through crosshatched wire

Consider the crosshatched current-carrying wires depicted: The shorter wires have been placed on top of the longer wires. Each wire can facilitate a maximum of 170 amperes of current and contributes a small amount of resistance to the circuit. Note that wires carrying 170 A are parts of separate circuits that include more elements than the wires depicted (e.g., a battery).

Since the conductors are touching, is there any way to predict how current will flow across the ‘bridge’ that is formed?

• Is your purpose to spread out the load, to avoid burning up wires? – analogsystemsrf Jun 15 '17 at 4:09
• @analogsystemsrf Precisely! I also need to maintain a rectangular shape marked by parallel sides and 90° angles. – gen-z ready to perish Jun 15 '17 at 4:10
• Each length of wire can be modeled as a resistor whose resistance is proportional to its length. I mean the length to the crossing point. The actual resistance can be calculated using the bulk resistivity of the conductor. I would suggest you load it into spice and see what happens. However, in order to find out how much current is flowing you will need to supply the whole circuit. – mkeith Jun 15 '17 at 4:35
• @mkeith Will the current divide itself evenly through the two wires? That's more my focus – gen-z ready to perish Jun 15 '17 at 4:36
• the resistances will not be identical because the lengths are not identical. Calculate the resistance of each segment of wire, proportional to its length. – Neil_UK Jun 15 '17 at 5:00
