What is the factors determining induced emf in dc machine?
In simple, number of turns of armature, intensity of magnet and speed of machine are major factor affecting induced emf in dc generator. If speed is increased, voltage will be increased simultaneously. Also Voltage is greater if number of turns are increased. Electro-magnet in the poles of a DC Generator also play an important role in the induced EMF. If intensity of magnet is exceeds, voltage also increased as well.
If a transformer has 1000 turns of wire in the primary coil and 50 turns in the secondary coil if the input voltage is 2400 V what is the output voltage?
120 v
A step-up transformer has 300 turns on the primary coil and 90000 turns on the secondary coil if the current flowing through the secondary is 5 amps what is the current flowing in the primary?
If a step-up transformer has 200 turns on the primary coil and 3000 turns on the secondary coil, with a primary coil voltage of 90 volts and current of 30 amps, then the turns ratio is 200:3000, so the secondary voltage is 1350 voltage and the available current is 2 amps. (This ignores losses through the transformer.)
Working principle of ammeter?
An ammeter consists of a coil with very low resistance. when electric current flows through the coil, the coil induces a magnetic field which turns the needle.
A stepup transformer has 100 turns on the primary coil and 500 turns on the secondary coil If the primary voltage is 120 volts what will be the secondary voltage?
A step-up transformer has 100 turns on the primary coil and 500 turns on the secondary coil. If there is 120 volts and 10 amps on the primary, what will be the current in the secondary? 2 amps.600v 2A
What causes inductance in a circuit?
Transformers........ you can make coil with few turns to produce required inductance.Another AnswerInductance occurs in ALL circuits. But it can be increased by winding a conductor to form a coil. It can be increased even further by using a ferromagnetic core within the coil.
How many turns of wire in a coil to produce 240V?
it depends on what is your low volatage. the turns of coil it's according to what is the voltage they are,When the coil / coil is equail voltage/voltage
What is the relationship between the stength of an electromagnet and the number of turns in the coil?
As the number of turns in the coil increases, the strength of the electromagnet increases.
Why deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increases?
Deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increase because as the number of turns in the coil increases the strength of the magnetic field also increases.
What are the three ways in which the strength of induced emf in electric generator can be increased?
Increase the current, increase the windings and increase the metal core mass.

How does the no of turns in a coil affect the production of electrical energy?
A coil doesn't produce electrical energy, but it can store it. For a given current (amperes), the energy storage in a coil is proportional to the coil's inductance, which in turn depends on the coil's length, diameter, and number of turns. With everything else staying constant, the coil's energy storage capacity increases when the number of turns increases.
How can you increase the field strength of an electromagnetic?
Magnetic field induction B = ur uo n I ur is relative permittivity of the core n the number of turns I the current through the coil So by increasing current or the number of turns B can be increased. By using a core with larger value of ur B could be increased
If a transformer has 1000 turns of wire in the primary coil and 50 turns in the secondary coil if the input voltage is 2400 V what is the output voltage?
120 v
Describe two ways to induce a larger voltage when you move a magnet in a coil of wires?
Speed of movement of coil and the number of turns in the coil
What coil will be greater if the primary coil of a transformer has 40 turns and the secondary coil has 60 turns?
The voltage ratio is 2:3. So for every 2 volts in you'll get 3 volts out. Secondary = 1.5 x Primary Voltage.
What is the mininmum number of turns required to make a coil?
One
