What is the difference between a series ohmmeter and a shunt ohmmeter?
Basically, your series and shunt ohmmeters differ in circuit configuration. Your series ohmmeter is configured in a way that your "meter" (which has internal resistance) is connected in series to your "measured resistor" and we all know that those TWO resistances will ADD up causing some sort of inaccuracy. While on the other hand, your shunt ohmmeter is configured in a way wherein your "meter" is connected in PARALLEL to your "measured resistor" that will ease-up the inaccuracy but will only measure resistances ranging from 200 Ohms to 400 Ohms (typically and depending on your configuration).
1. In Shunt generators armature current is equal to sum of field current and load current whereas in series generators field current and load current is same. 2. Shunt generators field winding has high resistance and large no of turns as compared to series generators. 3. Shunt generator field winding has thin conductor and series generator has thick.
A Stab-Shunt wound motor is a type of compound motor. Is has a field in series with the armature and also a field in parallel (shunt). You can tell the difference between the leads as the field in series with the armature has to be able to handle the amperage load of the armature itself. It will have leads identical in size to the armature. The key issue to watch for is wiring the shunt…
The difference between a separately excited DC generator and a Shunt DC generator is that for a separately excited Dc generator , the excitation field winding is supplied by an external source different from that supplying the armature while for shunt generator, the excitation field windind is connected in series with the armature and supplied by a single source.
there are four general type of feedback in amplifiers... called feedback topologies 1.voltage sampling series mixing also called series-shunt feedback 2. current sampling shunt mixing also called shunt-series feedback 3.current sampling series mixing also called series-series feedback 4.voltage sampling shunt mixing also called shunt-shunt feedback
Be certain the circuit is de-energized and discharged before connecting an ohmmeter. Do not apply power to a circuit while measuring resistance. When you are finished using an ohmmeter, switch it to the OFF position if one is provided and remove the leads from the meter. Always adjust the ohmmeter for 0 (or ∞ in shunt ohmmeter) after you change ranges before making the resistance measurement.
The DC voltage for the amplifier (transistor or FET) runs for a series-fed oscillator through the inductance of the LC circuit. A shunt-fed oscillator uses a radio-frequency choke or a resistor to deliver DC voltage to the amplifier. For an oscillator the difference between serial-fed and shunt-fed is small. The choke resonance frequency can interact with the LC circuit resonance frequency. This problem happens only with shunt-fed. Furthermore series-fed needs less components. Therefore it is…
Explain the way anatomical shunt through the bronchial circulation causes an PO2 difference between alveolar gas and arterial blood.?
A series motor is one in which the field windings are in series with the armature windings. So the torque is proportional to the square of the supply current. 'Shunt' is an archaic term for 'parallel'. So a shunt motor is one in which the field winding is in parallel with the armature windings. So the torque is proportional to the supply current.
A shunt dc motor has quite different characteristics from a series motor. Wired in series, the same current passes through the armature and the field winding and it is most unlikely that a shunt motor would have a field winding that is suitable for this. Therefore a shunt motor cannot be wired as a series motor in general because its field winding is designed for only a small current.
