True or False: In a parallel circuit, the current through each resistance varies while the voltage across each resistance is the same.

True or False: In a parallel circuit, the current through each resistance varies while the voltage across each resistance is the same.

• A. True
• B. False
• C. Sometimes true
• D. Cannot be determined

Answer: (A)

In a parallel circuit, all components share the same two nodes, which means they are connected across the same voltage source. As a result, the voltage across each resistor in a parallel circuit is indeed the same. However, the current flowing through each resistor can vary depending on the resistance value of each device according to Ohm's Law (V = IR). Since each resistor may have a different resistance, the current will adjust in order to maintain the constant voltage across each one. Therefore, saying that the current through each resistance varies while the voltage across each resistance is the same accurately reflects the behavior of a parallel circuit.
