I want know which is the correct way to approach problems where we have to identify CC and CV mode.

Let us consider a question -

For various load resistors, connected across \$Channel-1\$ of the DC power supply the following table is obtained-

Now we have to determine what modes are a, b, and c

I have done this problem in two ways-

First: Since V is constant and load current is changing with values of load resistance so, a,b, and c must all be in CV mode. But here I am not considering the fact that in the third reading load is drawing more current than the ratio \$V/R_L\$.

Second: Is based on this text that I have recently read, here they have given the graph-

I will plot the values of V and I and see which operation line it is following(CV or CC), but for the third reading, we find that \$R_L\$ is greater than \$R_c= V/R_L \$, it will lie on CV mode line. Checking for first and second reading as well, I get all a, b, and c in CV mode.

So, which method is more correct and general such that I can apply it on all such problems?

Also what do they mean by this?-

A power supply will operate in constant voltage (CV) mode provided the load does not require more current than the current limit setting.

Please let me know if the second method is correct approach or not.

I want know to which is the correct way to approach problems where we have to identify CC and CV mode.

Let us consider a question -

For various load resistors, connected across $Channel-1$ of the DC power supply the following table is obtained-

Now we have to determine what modes are a, b, and c

Now a simple approach goes to, since V is constant and load current is changing with values of load resistance so, a,b, and c must be a constant voltage mode.

  But I have another approach as well according to the definition given in this text-

I will plot the values of V and I and see which line it is following, but for the third reading, we find that \$R_L\$ is greater than \$R_c\$, it will lie on CV mode line. Checking for all I get all a, b, and c in CV mode.

Can I think like both? Am I missing something in approach second?
