Question by Amanda: I need to get interested in some kind of hobby or good pass time?
I find myself having nothing to do all the time. I do all my college work then I just sit on the computer all night. What is something fun and/ or interesting to get involved in. I am 19 and a junior in college, I am trying to be more healthy and fit as well so if there are any activities that involve bettering yourself I am up for it as well. Thanks!

a model electric train makes one complete pass around a circular track every 15 seconds….?

Question by moniquew93: a model electric train makes one complete pass around a circular track every 15 seconds….?
a model electric train makes one complete pass around a circular track every 15 seconds. the train’s motor has a resistance of 6.0ohm and is connected to a 70.0V source. How much energy will the train use in 12 complete passes around the track?

Answer by kirchwey
This question cannot be answered. Model-train motors don’t draw the huge wattage implied by the voltage and resistance, which = V^2/R = 816.67 W. At running speed the motor would generate a back EMF which would substantially reduce the actual voltage across the internal resistance. See the ref.
EDIT: The input data are not necessarily crazy, just incomplete. What’s crazy is the assumption that the given V is applied across the given R continuously; it actually would only happen momentarily at startup.

Question by Knights Templar: does electricity pass through the tracks on a electric train?
what creates the circuit with overhead wiring on electric trains and if it passes through the tracks why whats stops electrocution of people walking on tracks

Best answer:

Answer by Bob B
The high voltage to drive the train is carried on the conductors hung above the trackway. Since the tracks only provide a path to carry the current to ground, they aren’t at an elevated voltage level.
