Wholesale Globes

If the current is different everywhere in a parallel circuit, globes glow differently everywhere?

Because current in parallel circuits is different everywhere, does that mean that some light globes will glow brighter than others? I assume my house is in parallel because i can isolate different sections, but then wouldn't that mean that some of my lights dont glow as brightly as others?

1. All lights, and receptacles that share a common circuit, are wired in parallel with one another (or at least they are supposed to be). It is true that as you turn on different combinations of lights that share a common circuit, the current is of a different magnitude in different parts of the circuit. If a circuit with multiple lights or other loads is fully loaded, the voltage will be a little lower at the end of the circuit than near the source, due to current flowing through the resistance of the conductor which causes voltage to gradually drop along the length of the circuit. As long as your house is wired to code (NEC) however, the drop in voltage should not be noticeable when observing the output of any lamp in your house. The voltage drop from utility transformer to any load, under any condition should not be greater than 5%.
2. Each feed off the main circuit (each parallel load) may have different currents depending on the load. A 40 watt lamp draws less current than a 100 watt. But if all loads (lamps) are identical, they will all burn as brightly as each other.
3. All depends upon the voltage !
