Circuit macros was specifically developed to “draw” circuit diagrams. Using it to do just that is an absolute plessure. See the below sections for examples on:

• Simple series and parallel resistive circuits
• Nodal analysis circuits
• Mesh analysis circuits
• A combination of nodal and mesh analysis circuits
• Source transformations
• Superposition
• Thévenin and Norton equivalents

Simple series and parallel resistive circuits

If the source current of $v_s$ is know, solve for $R_x$

With $i_x$known, use current division to determine $v_{R_3}$

With 5 A flowing through $R_4$, solve for $v_x$

Find the current value $i$ and voltage value $v$.

Find the current values for$i_1$ and$i_2$

Nodal analysis

Use nodal analysis to find the voltage values $v_a$ and $v_b$, and then use this to find the current value,$i_{R_3}$.

Use nodal analysis to solve for $v_a$ and $v_b.$

Use nodal analysis to solve for $v_a$ and $v_b.$

Use nodal analysis to solve for $v_1$, $v_2$ and $v_3$, and use these values to solve for $I_q$

Mesh analysis

Use mesh analysis to solve the mesh currents,$i_a$, $i_b$ and $i_c$.

Use mesh analysis to solve the mesh currents, $i_1$, $i_2$ and $i_3$

Use mesh analysis to solve the mesh currents, $i_1$, $i_2$ and the super mesh current $i_3$

Nodal and mesh analysis

Use nodal analysis to solve node voltages $v_1$, $v_2$ and $v_3$ and mesh analysis to solve the mesh currents, $i_1$, $i_2$ and $i_3$, and check your answers.
