I'm making a wearable project that involves me wiring up about 16 LEDs into a piece of clothing. Unfortunately, it's been many a year since I took a physics course and I'm a little rusty on things. Here's my situation: The LEDs drop about 2V each, and are meant to be used with a current of...

I attached the problem. I'm pretty confused. I remember the equations for parallel and series circuits, but I have no idea how to do this. I attempted, but failed. I know the two 10 ohm resistors are in parallel (so Rnet is 5), and the 20 ohm and the 6 ohm resistor are in series (So Rnet is 26)...

I am curious to know, why on a electromagnet that the wire coming in is on the opposite side to the wire leaving? Is it due to the way the current comes in and leaves, as in the anticlockwise field in the north so incoming and the outgoing is clockwise south. When I say a electromagnet I...

i have a 20 year old electric garage door motor that i cut out of the housing and kept but threw away the rest as garbage. now that i want to use the motor, i have no recollection of how the wiring worked. it is a very clean basic motor made by samsung. it's a 120 volt, 5 amp, single phase...

I recently purchased an old small drill press. It hosts a retasked old washing machine motor as the power source. Only problem is that the wiring was snafu, and I could use some help with that. This is a FSP motor, 115 volt 1725 rpm, 1/3 horsepower. The motor input wiring are to a set of...
