    Hit or miss engine igniter

    The combination of the capacitance of the condenser and the inductance of the coil make a tuned circuit. When the points open, the tuned circuit oscillates, producing a longer spark time. Also, since the output voltage is now AC instead of 1 DC pulse, the metal pulled from one side of the...

    I wanted to access my account to manage my license. However, my password did not work. So Mach locked me out after a few attempts. My ip is still blocked days later.

    off topic but questions about battery plates materials

    Current capacity depends on surface area of electrodes. Voltage depends on electrode materials, and choice of electrolyte(s). In operation, the zinc will oxidize creating a zinc salt which dissolves into the electrolyte. EG: if using sulfuric acid as the electrolyte, zinc sulfate will be...

    off topic but questions about battery plates materials

    Look at the table of standard electrode potentials. This will give you an idea of what voltages to expect from different metals. For example: A copper (Cu) electrode has a potential of about +.52 volts. A zinc (Zn) electrode has a potential of about -.76 volts. Together, with an appropriate...
