What else can I help you with?
Which has a highest resistance between shunt resistor and series resistor?
If you are placing more than one resistors in series, then its combined resistance is higher than when you place these resistors in shunt.
Which is more efficient between series and shunt regulator and why?
Series regulators are generally more efficient than shunt regulators because they control the output voltage by varying the resistance in series with the load, minimizing wasted power. In contrast, shunt regulators divert excess current away from the load, often resulting in higher power dissipation and reduced efficiency, especially under varying load conditions. Therefore, for applications requiring better efficiency and stable output voltage, series regulators are typically preferred.
What happen in shunt motor speed if the resistance is increased?
Its performance becomes worse. The speed will drop more when a mechanical load is put on the shaft.
What is the working principle of a DC shunt motor?
To ensure that the Lathe machine's motor working properly, DC motor starter is added in which it used to protect motor against damage from: • short-circuit, • long term overload, • excessive starting current, and yet to made the operating speed of motor easily to be control by operator. During starting, the motor is not turning, hence there is no internal voltage .The internal resistance is very low and thus the current flow through is very high. This condition may cause damage to the motor Hence, a staring resistor is added in which connect in series with the armature to limit the current flow until the internal voltage of motor is increasing to do the limiting. In order to prevent losses as the speed of the motor is build up; the starting resistor should be removed
Are wire wound resistors used in parallel circuits?
Can be. Wire wound resistors might take more power, or offer better precision, or custom resistance values. Wherever, whenever those features are desirable, whether its a series or parallell circuit, a wire wound resistor might be used.
What is difference between stab shunt dc motor and shunt dc motor?
A series motor respond by decreasing its speed with small increase in current for a given load torque. A shunt motor holds its speed nearly constant with large increase in input current for same amount of load torque
Why the armature voltage E changes when the field rheostat is varied?
This depends on how the motor and wiring. You'll need to provide more information. Series / compound / shunt / differential / self or separately excited / is the rheostat in parallel or series to the field / is the rheostat on the shunt field or series field (if compound)
Does series field winding have more resistance or a shunt field winding?
shunt field winding have more resistance than series field winding ************sai ganesh ************269*******
What is the difference between shunt and series regulator?
Basic voltage regulators are classified as either SERIES or SHUNT, depending on the location or position of the regulating element(s) in relation to the circuit load resistance.
Which has a highest resistance between shunt resistor and series resistor?
If you are placing more than one resistors in series, then its combined resistance is higher than when you place these resistors in shunt.
Why speed control of DC shunt motor is necessary?
The total voltage of the batteries or DC power source connected to a shunt motor affects how first it moves. Increasing the DC voltage will make the shunt motor run faster.
What is the difference in series type and shunt type ohmmeter?
In a series type ohmmeter, the current passes through the resistance being measured, while in a shunt type ohmmeter, the current is diverted around the resistance being measured. Series type ohmmeters are usually less accurate but simpler, while shunt type ohmmeters are more accurate but more complex.
What is the difference between cumulative and differential connections of dc compound motor or generator?
Well, sweetheart, the difference between cumulative and differential connections in a DC compound motor or generator lies in how the series and shunt fields are connected. In cumulative connection, both series and shunt fields aid each other, resulting in higher overall field strength. In differential connection, the series and shunt fields oppose each other, leading to a weaker overall field strength. So, pick your poison, depending on whether you want more power or less power.
Can you describe the speed of Dc series wound motor as a function of the series resistance of armature?
resistance of the armature is more related to the current going thru it 250v Dc 5hp motor 20 a 12ohms 1/2hp 2 amps 120 ohms the speed will be related to the number of poles
