When the current in a combination circuit reaches a node, the current is blocked.

When the current in a combination circuit reaches a node, the current is blocked.

• A. True
• B. False
• C. Depends on component values
• D. Only in DC

Answer: (B)

Currents at a junction follow Kirchhoff's current law: the total current entering a node must equal the total current leaving. That means the current that arrives from one branch splits into the available paths based on the branch impedances, not that it gets blocked. In a DC circuit, this division is inverse with resistance; in AC, it follows the impedance of each path, but the current always has a way to continue unless a branch is open. The node itself doesn’t block current—blocking would only occur if a particular path is open or has infinite impedance. So the idea that current is blocked at a node isn’t correct, because current is distributed among the connected branches rather than stopped.
