Circuit Board 91002: DC Network Theorems


Consisting of nine training circuit blocks and a constant-source current block, the DC Network Theorems ­Circuit Board enables students to perform practical exercises that demonstrate theoretical DC principles. When a circuit has two voltage sources in different branches, theorems are used to solve for voltage and/or current in these circuits where Ohm’s Law cannot be applied.
