Nettet14. jan. 2024 · When the wires are connected, it forms a short circuit, with extremely high amounts of current flowing through the wire due to the negligible resistance of wires. This causes sparks. The bulb has non-negligible resistance, and since voltage is constant and V=IR, there is less current flowing through the wire, so there are no sparks. Share. Cite. NettetAC motors are simple because the alternating current does all the work. By sending the current through a stationary wire that surrounds a shaft, you create a varying magnetic field, which in turn rotates the shaft. Remember, AC electricity goes from “positive voltage” to 0 to “negative voltage” at double your frequency (Hz) every second.

So if work done is negative, time taken is positive, then power is negative. This would mean that the object is losing energy. On the other hand, positive power would mean that the object is gaining energy. Duality. psychiatrists madison wisconsin
