When two parallel branches reconnect at a node after flowing through the branches, the currents combine to form what?

When two parallel branches reconnect at a node after flowing through the branches, the currents combine to form what?

• A. A separate loop with no connection
• B. An unpredictable current
• C. The product of voltages
• D. The supply current

Answer: (D)

When parallel paths reconnect at a node, the currents from each path must combine to continue back toward the source. This follows the idea that charge is conserved: the current entering the node from the branches equals the current leaving toward the supply. In a simple two-branch parallel setup, the branch currents add together to form the current drawn from the source—the supply current. The voltage across both branches is the same, but the currents split according to each branch’s resistance; when they reconnect, those currents sum again on the return path.
