Consider the following circuit, where 0 \leq R_o < \infty.

Part a. Determine the value of I_o when R_o = 3 ohms.

Enter I_o (in Amps):

Part b. Choose R_o so that V_o = 30V.

Enter R_o (in ohms) or None if no such R_o exists:

Part c. Choose R_o so that I_o = 6A.

Enter R_o (in ohms) or None if no such R_o exists:

Part d. Choose R_o so that V_o = 75V.

Enter R_o (in ohms) or None if no such R_o exists:

Consider the following circuit where the resistance R is in the range 0 \leq R < \infty.

Part a. Determine the value of i_1 when R=0\Omega.

Enter i_1 (in Amps):

Part b. Determine the potential of e_1 (relative to the labeled ground node) when R=1\Omega.
