Engineering (Science & Mathematics) - February 2007

6 cells are connected in series to form one battery. Ea cell has a rating of 1.5V and 1A. AWG 18-ga wire joins the + terminal of the battery formed by the series to an indicator lamp located 300ft away. another 300ft length of AWG 18ga wire runs from the lamp back to the battery's neg pole. The lamp acts as a 50 ohm resistor.
1. total voltage and amperage supplied by battery?
2. total resistance resulting from 600ft of 18ga wire?
3. total voltage drop across wire?
4. total voltage drop across lamp?

Please show formulas used to calculate answers. Stuck on this one bigtime.

Thanks!

Why we do not use air-ships today ?

I think we should start using air-ships again with some augmented technology. Though we won't get the speed of jet liners, those air-ships are really good means of transportation.

If you have a clock motor, and you want to find out how many milliamps it is. How could you ...?

If you have a clock motor, and you want to find out how many milliamps it is. How could you derive it from the known variables = motor is 120 volts/at 60 hertz, 4 watts / 5 revolutions per minutes/ and (cw/ccw) "whatever that means",and is there an equation to do it?
