    How Do I Calculate Voltage Drop Without Knowing Current?

    Homework Statement 230 V, 50 Hz supply (TN) Ze = 0.8 ohms Z1 = 8.9 milli-ohms/meter Z2 = 14.5 milli-ohms/meter Volt-drop/Amp/meter = 18 mV/A/m Homework Equations Zs = Ze + Z1 + Z2 V / Zs = I ? The Attempt at a Solution Zs = Ze + Z1 + Z2 Zs = 0.8 + (0.0089 + 0.0145)X......where X is the...

    How Do I Calculate Voltage Drop Without Knowing Current?

    Hi all Wondering if anyone can help. Really don't know where to start I know Zs = Ze + Z1 + Z2 and Z1 = PCR 8.9 milli-ohms/meter and Z2 = CPC 14.5 milli-ohms/meter which equates to 0.0234X milli-ohms/meter over X meters but where does my volt drop come in if I don't know my current? Regards
