The unit was used in the artificial heart pacemaker a device created to produce electrical shocks to the heart to maintain a healthy heart rate.

Who invented a resistor to reduce cost of producing electric controls. Unlike lamps they do not produce light but they do produce heat as electric power is dissipated by them in a working circuit. An ac motor is an electric motor driven by an alternating current ac. Essentially there are two types of electrical power real power and reactive.

The resistors with more resistance value will reduce large amount of electric current whereas the resistors with less resistance value will reduce less amount of electric current. Typically though the purpose of a resistor is not to produce usable heat but simply to provide a precise quantity of electrical resistance. Can i use a resistor to slow down a dc motor.

Will it be a good idea to connect a resistor in series with the motor and the battery in order to reduce the motor speed. Otis boykin is best known for inventing an improved electrical resistor used in computers radios television sets and a variety of electronic devices. Boykin invented a variable resistor used in guided missile parts and a control unit for heart stimulators.

Back in the early days of electricity street trolleys were driven by electricity and the speed controlling was done by moving. Capacitors can be used for power factor correction. It stores electricity so no it does not reduce electricity.

Ask question asked 2 years 10 months ago. The rotor magnetic field may be produced by permanent magnets reluctance saliency or dc or ac electrical windings. Wiki user september 13 2011 415pm.

Fuel cell cars are unlikely to be affordable in the near future. United electric controls provides gas leak detectors pressure switches temperature switches safety transmitters and sensors for the process discrete semiconductor aerospace and defense industries. Who invented a resistor tor reduce the cost of producing electric controls.

Resistor schematic symbols and values. The electric current reduced or restricted by the resistor is measured in ohms and it is represented by a symbol w. The ac motor commonly consists of two basic parts an outside stator having coils supplied with alternating current to produce a rotating magnetic field and an inside rotor attached to the output shaft producing a second rotating magnetic field.

In electronic circuits resistors are used to reduce current flow adjust signal levels to divide voltages bias active elements and terminate transmission lines among other useshigh power resistors that can dissipate many watts of electrical power as heat may be used as. The cost of producing a kilowatt of power with a fuel cell will be less than 30 in 2015. Fuel cell cars reduce use of non renewable fossil fuels.
