    Speed Reduction, Torque, high Rpms's?

    hello, i am unsure if someone will be able to help me with this? If you have a motor running at say 3000 rpm's, and the torque "needed" is more than the motor has to offer. Can you do a gear reduction to get more torque, and gain "all or most" of the lost rpm's back after reduction is made...

    Car Battery Amps: Understand & Calculate for Your Vehicle

    i googled and learned to use the formula Watts x volts = amps, how are you getting 10 watts from a 100 watt bulb if you don't mind, from what I've read I've learned to do it like this. 100 watt bulb at 120 volts draws 100/120 = .8 amps 100 watt bulb at 12 volts draws 100/12 = 8.3 amps or you...

    Car Battery Amps: Understand & Calculate for Your Vehicle

    i think you can do it this way to? take the 45 amps * 12v to get 540 watts, so we know the bulb is 100 watts, so i guess the bulb uses 100 watts per hour, which means it would last, estimating in my head, looking at the battery which is 540 watts, id say it would run little over 5 hours? does it...

    Car Battery Amps: Understand & Calculate for Your Vehicle

    i was reading something on the web and was wondering if this could be right, knowing the battery is 45 amps, and i am using around an 8 amp bulb, i would assume 8 amps is how much the bulb uses per hour? if so, 8/45 = around 5.6 hours? could this be right?
