You know the load impedance and load current. How will you determine the active and reactive power associated with the load?eehelp150 said:
Load impedance = 5 + j6cnh1995 said:
Yes. Take magnitudes only.eehelp150 said:
So 144 * (5+j6)cnh1995 said:
Yes.eehelp150 said:
Yes. Can you say why?eehelp150 said:
Is it because it's 1/3 of the "actual" circuit?cnh1995 said:
Well, you calculated the total power for three phases. So, you should multiply the load power by 3. But they are not equal because out of total input power, some power is associated with the line impedance 1+j2 ohm. Remaining power is fed to the load.eehelp150 said:
If the prompt is:cnh1995 said:
You should multiply by 3. You have transformed the circuit into its per phase equivalent. Total power will be thrice the per phase power.eehelp150 said:
Here, while applying S=I2Z, you should consider the magnitude only. If you want to use the phasor form, you should take the conjugate of the current i.e. (IZ)(I*).eehelp150 said:
If the prompt is:cnh1995 said:
So magnitude of (5+j6) = sqrt(61)?cnh1995 said:
eehelp150 said:
For load power factor, you can use the single phase equivalent network since it is a balanced network.cnh1995 said:
Yes.eehelp150 said:
so load would be 3 * 144*sqrt(61)?cnh1995 said:
If the load impedance is R+jX, what would its power factor?eehelp150 said:
Supplied complex power from source refers to the total power that is generated and delivered to a load, while consumed by load refers to the total power that is actually used by the load. In other words, supplied power is the total amount of power available, and consumed power is the amount of power that is actually used.
The main difference between supplied complex power from source and consumed by load is that supplied power is the total amount of power available, while consumed power is the amount of power that is actually used. This means that there may be a difference between the two values, depending on the efficiency of the system and any losses that may occur during transmission.
Supplied complex power from source and consumed by load are typically measured in watts (W) or kilowatts (kW). In some cases, they may also be measured in volt-amperes (VA) or kilovolt-amperes (kVA). These measurements can be obtained using specialized power meters or calculated using various electrical formulas.
The supplied complex power from source and consumed by load can be affected by a variety of factors, including the efficiency of the power source, the quality of the electrical components, the type of load being supplied, and any losses that occur during transmission. Additionally, the distance between the source and load, as well as the type of wiring and connections used, can also impact these values.
Understanding the difference between supplied complex power from source and consumed by load is important for several reasons. Firstly, it allows for more accurate measurement and monitoring of power usage, which can help identify areas for improvement and potential cost savings. Additionally, it can help ensure that the load is receiving enough power to function properly and avoid overloading the system. Finally, it can also help identify any issues or losses in the electrical system that may need to be addressed.
