Hi

Kindly help me in understanding the difference between RLOAD1 and RLOAD2?

I have seen the mathematical formula differs between both

My question is when to use RLOAD1 and when to use RLOAD2?

How it will make a difference in the analysis?

Also kindly share an example by using RLOAD 1 AND RLOAD2

Thanks in advance

RLOAD1 is for real/imaginary numbers and that RLOAD2 is for magnitude/phase numbers.

Hi

Thanks for your reply

I see the formulas are different refer below

I want to know for same load given as RLOAD1 AND RLOAD2 cards how will it affect the output

Kindly provide me with an example analysis using RLOAD1 & RLOAD2

Refer formulas below

The difference between RLOAD1 and 2 only come into play if you are interested in defining the load as frequency dependent on either magnitude/phase or real/imaginary. If you are not going to mess with the phase of the applied load, then the two can be used interchangeably.
