Which circuit configuration involves components connected so that they share the same voltage across each resistor and current divides?

• A. Resistors in Parallel Circuits
• B. Resistors in Series Circuits
• C. Complex Circuits with a Voltage Drop
• D. Open Resistors

Answer: (A)

When components share the same voltage across each resistor and current divides, you’re looking at a parallel circuit. In a parallel connection, each resistor is connected directly across the same two nodes, so the voltage across every branch is identical to the source. Since the voltage is the same for each resistor, the current through each branch is determined by I = V/R, meaning branches with lower resistance carry more current and the currents add up to the total from the source. This division of current among branches is the hallmark of parallel connections. By contrast, in a series circuit the current is the same through every resistor and the voltages divide among them, and an open resistor would block current altogether.
