Taking the slide rheostat's value as the design variables and the battery voltage and the maximum resistance of the slide rheostat as constraint conditions and maximizing the brightness of the light bulb as the optimization objective, an optimization model can be constructed.
where I is the current value of the circuit, R is the biggest resistance of the slide rheostat, U is the voltage of the battery pack, and R1 is the resistance of the bulb.
When the motor current reaches a pre-defined current limit (such as 190 percent or 250 percent), the speed drops, but it recovers more quickly than with the liquid rheostat, according to the company.
As a solid-state piece of equipment, the SPR drive does not require the same maintenance associated with a liquid rheostat device, and no cooling tower is needed, according to Quad Plus.
The use of storage cells to supply current to the comparator has not been contemplated, and the regulating rheostats have such ranges of resistance as to permit the use of dry cells having an initial emf of not over 1.
The much-used indicator B and its rheostats are placed at the right, and the reading in the unknown-cell window, nearby, plus the reading of indicator B equals the value of the unknown emf.
With the rheostats
properly set, a tap on any of the momentary control switches will move focus about 0.
People think AC drives and liquid rheostats
are maintenance free, but they require just as much service as a DC System.
Typical applications for the PIC12C508 and PIC12C509 include personal care appliances, remote transmitters, sensors and detectors, portable voice recorders, security systems, transponders, RF tags, rheostats
and rechargeable battery modules.
