When two loads are connected in parallel, what can be said about the voltage across each load?

• A. It is half of the supply voltage
• B. It is equal to the supply voltage
• C. It is twice the supply voltage
• D. It varies depending on the load

Answer: (B)

When two loads are connected in parallel, the voltage across each load remains equal to the supply voltage. This characteristic is a fundamental principle of parallel circuits. In parallel configurations, all components share the same two nodes, creating multiple paths for current, while the voltage across each path (load) is consistent with the source voltage. This means that, irrespective of the resistance or impedance of the individual loads, each one experiences the full supply voltage. For instance, if the supply voltage is 120 volts, then each load connected in parallel will also have 120 volts across it. This behavior contrasts with series circuits, where the voltage is divided among the loads based on their individual resistances. Thus, the key takeaway is that in a parallel connection, all loads see the same voltage, which is equal to the supply voltage.
