What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
Why transformer power expressed in KVA?
because of its losses i.e iron and copper losses. since iron loss depends on voltage (v)and copper loss depends on current(i).
Is core loss same as no load loss in transformer?
Yes, that is almost true, apart from a very small copper loss in the primary winding that carries the small magnetising current. The core loss (iron loss) depends on the applied voltage. This loss is measured by the open-circuit test, carried out at the working voltage.
What is the power loss in watts of a conductor that carries 24Ampere and has voltage drop of 7.2Volts?
Power = voltage times current 7.2 volts * 24 amperes = 172.8 watts
How does Lenz's Law explain power loss in transformers?
It doesn't, really. The power loss in transformers is broken down into copper loss and iron loss. The copper loss comes from the resistance of the windings in the transformer and depends on the load current, while the iron loss in the magnetic core depends on the magnetic flux density and is constant if the supply voltage is constant.
What is the difference between voltage drop and power loss?
voltage drop is the loss or drop that occured across the element so that voltage gets down and current increases across the element and power loss is like i2r loss and like wastage of power without consuming
What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
How many times can a 110v line be split without voltage drop?
A splice has a minor additional resistance associated with it, but the main reason for voltage drop will be length. The smaller the wire diameter, the higher the resistance per unit length. The type wire such as stranded or solid or copper and aluminum also contribute to voltage loss in various ways.
Electricians have another term for voltage drop in a cable What is it?
the formular notation for voltage drop is Ed Another possible term is "IR loss" meaning the current (I) x resistance (R) loss on the wire part of a circuit
Why transformer power expressed in KVA?
because of its losses i.e iron and copper losses. since iron loss depends on voltage (v)and copper loss depends on current(i).
What is the decibel loss of a signal that loses half its power during the course of transmission?
When the power (energy) is dropped to the value of 50 percent, the decibel loss is 3 dB, but the voltage is dropped to the value of 70.1 percent. Power drop to 50 % means -3 dB; that is 70.1 % voltage drop. Power drop to 25 % means -6 dB; that is 50 % voltage drop.
What are copper losses in a transformer?
Copper losses are purely voltage-drop losses (I squared R) caused by the resistance of the windings, as opposed to hysteresis losses and eddy current losses (so-called iron losses), which are magnetic in nature. They are called copper losses whether the winding conductors are made of copper or not, by the way.
Is core loss same as no load loss in transformer?
Yes, that is almost true, apart from a very small copper loss in the primary winding that carries the small magnetising current. The core loss (iron loss) depends on the applied voltage. This loss is measured by the open-circuit test, carried out at the working voltage.
Why is it using low resistance coils in transformer minimize power loss?
To avoid voltage drop in the coil.
What is the total copper loss when rotor is standstill?
It is the supply voltage divided by the rotor resistance including the resistance of the brushes.
How does voltage change across an appliance in a parallel circuit?
With the minor voltage loss in the wiring, the voltage drop across a single appliance is the total voltage in the circuit, and doesn't change when more devices are added in parallel.
What is the power loss in watts of a conductor that carries 24Ampere and has voltage drop of 7.2Volts?
Power = voltage times current 7.2 volts * 24 amperes = 172.8 watts
