The voltage and current for an unidentified circuit element w/ 2 terminals are zero for t < 0. For t >/= 0 they are
v = 50 e^(-1600t) - 50 e^(-400t) Volts
i = 5 e^(-1600t) - 5 e^(-400t) Amps
How much energy is delivered to the circuit element between 0 and 625 microseconds?
Note: Current is flowing in the direction of a voltage drop.

Note that I'm to find the total energy over a specified period of time. I think I need to integrate over the interval 0 to 625 microseconds, but I tried that and I can't seem to get it right.

A tank is filled by three pipes with uniform flow. The first 2 pipes operting simultaneously fill the tank in the same time during which the tank is filled by the third pipe alone. The second pipe fills the tank 5 hrs faster than the first pipe and 4 hrs slower than the third pipe. Find the time taken by the first pipe alone to fill the tank.
No comments plz.

I'm operating a carpet cleaning machine that has an onboard heater. That heater is rated 15 amps. It SEEMS to operate in a cyclical fashion; only heating enough to maintain a certain temperature.

Sometimes I use the machine and the water is hotter than normal. As a carpet cleaner, naturally I want the hottest water possible.

Question: Does the amperage of the house current (15 or 20 or 30) make a difference to the heating element and the heat of the water it puts out? We're currently under the illusion that the higher the house current in amps, the hotter the water gets. This doesn't seem right...?
