What is shunt and series motor?
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.
Which motor has high starting tourque?
Series motors have the highest starting torque. The torque is proportional to the square of the current, and the starting current is so high it has to be limited by a resistor called a rheostat. Series motos are used mainly on trams and trolley buses.
Current in a circuit is inversely proportional to?
In a circuit , current is inversely proportional to the resistance.
Current is inversely proportional to resistance?
Current is inversely proportional to resistance, this comes from the ohms law. V=IR If we keep the voltage as constant then Current will be inversely proportional to resistance
Relation between voltage speed and current in alternating current motor?
voltage is inversly proportional to speed speed and current are directly proportional to each other but voltage and current are directly proportional to each other..
Is torque directly proportional to applied voltage?
Current is directly proportional to applied voltage. Ohm's law.
Which motor has a higher starting torque?
A series-wound commutator motor has the best starting torque because the torque is proportional to the square of the current, and the starting current is set by a current-limiting resistor which is switched out as the motor builds up speed.
Is current proportional to torque?
Yes, current is generally proportional to torque in electric motors. The torque produced by a motor is directly related to the current flowing through its windings, as described by the motor's torque equation. This relationship holds true in many types of motors, such as DC and stepper motors, where an increase in current typically results in an increase in torque output, assuming other factors remain constant. However, the specific proportionality can vary based on the motor design and operational conditions.
Why the starting torque of a dc series motor is high?
load is heavier so starting torque is requiredAnswerBecause the same current is passing through both the armature and field windings, the torque is proportional to the squareof the current. Since the starting current is alway high (no back emf), the torque will be very high indeed.

What is the relationship between torque and speed for an electric motor?
Torque and speed are inversely proportional
Current is proportional to the potential difference and inversely proportional to its?
Current is proportional to the potential difference and inversely proportional to resistance. Ohm's law: Current equals voltage divided by resistance
Current in a circuit is inversely proportional to?
In a circuit , current is inversely proportional to the resistance.
Why induction motor current increase when load increase?
The slip is proportional to the load torque in an induction motor. This can also be seen as a reduction in speed causing extra current to be induced in the rotor to supply the increased torque.
Current is inversely proportional to resistance?
Current is inversely proportional to resistance, this comes from the ohms law. V=IR If we keep the voltage as constant then Current will be inversely proportional to resistance
