If the value of a dependent source (say CCCC) depend on the value of an independent source (say a current source). When setting the current source to 0, would that make the CCCC an open circuit (i.e. set to zero) as well?

Do you mean CCCS (current controlled current source)?

The answer is to treat the CCCS as you would any other source acting alone, i.e. generating it's specified current, say \$kI_x\$, which is dependent on the current in the nominated path, \$I_x\$. You must not use the trivial solution, \$I_x =0\$ at this stage; doing so is a common error.

  • \$\begingroup\$ Sorry I meant CCCS. Lets say that there is a current source providing current I1, and a dependent source (CCCS) which its current is equal to 3*I1. If we sat the current source to zero (I1=0; open circuit), wouldn't the CCCS be an open circuit too? \$\endgroup\$ – William Mar 24 at 4:13
  • \$\begingroup\$ No. Dependent sources are treated in the same way as independent sources. Note the final sentence of my answer. \$\endgroup\$ – Chu Mar 24 at 9:04
