In a parallel circuit, the voltage across each branch is equal to the total voltage.

In a parallel circuit, the voltage across each branch is equal to the total voltage.

• A. Equal to the source voltage
• B. Greater than the source voltage
• C. Less than the source voltage
• D. Equal to the total voltage

Answer: (D)

In a parallel circuit, all branches are connected across the same two nodes, so the potential difference across every branch is the same. That fixed voltage is provided by the source and is the total voltage available to the circuit. Therefore, the voltage across each branch equals the total circuit voltage, i.e., the source voltage. While currents split among branches according to each branch’s resistance, the voltage across each branch stays identical to the total voltage.
