Kirchoff's volage law question????

Question

Do you expect Kirchoff's voltage law to hold in circuits involving lightbulbs? What about the current junction law? Explain.

Answer 1

yes, in both AC and DC scenarios

Kirchoff's laws are central to electrical engineering. These laws are applied from massive electrical distribution systems to describing transistor behavior.

The voltage law decribes that the voltages around a closed circuit must sum to zero. An incandescent light bulb can be simply modeled as a resistor so that the supply voltage equals the voltage across the bulb (less any resistance losses in the wiring).

The current law states that the currents summed at any junction, or node, equal zero.
Consider light bulbs in parallel hooked up to a supply. The current from the supply is equal to the sum of the currents through the two bulbs.
