WebDear vv5553743, I am not an expert but here is my best guess. The contradiction you have found arises from the assumption that the resistance in the circuit is equal to 0. From Ohm's Law, we know that I = V/R. But this does not make any sense because we are dividing by zero (I = V/0). This is why maximum current can flow when there is not voltage. WebJun 11, 2024 · This means brief pulses of AC current can easily flow through a capacitor, while steady-state DC current is completely blocked. Share. Cite. Improve this answer.

WebAlternating current (a.c.) If the current constantly changes direction it is called alternating current, or a.c. Mains electricity is an a.c. supply. The UK mains supply is about 230 V. WebNov 27, 2024 · In an ac circuit, there is a phase angle between the source voltage and the current, which can be found by dividing the resistance by the impedance. The average power delivered to an RLC circuit is affected by the phase angle. The power factor ranges from –1 to 1. 15.6 Resonance in an AC Circuit

WebIt is cheaper but its maintenance is quite dangerous and costlier then AC. Hazard. The AC is less dangerous than DC because it reaches to 0V at some regular intervals. (not to be played with at high voltage) The DC is very dangerous and life-threatening then AC because it maintains a constant current flow.

WebOct 15, 2024 · If a resistor is placed across the live and neutral wires, the voltage across the resistor is alternating and thus, the current through the resistor is alternating. It's completely irrelevant to this result if the neutral wire is at 0V with respect to ground. But the wire isn't. You are applying 240v ac to the wire. centuria sydneyWebJan 12, 2024 · 1. DC current does pass through a capacitor. If you connect an ideal capacitor to an ideal current source, the current will flow through the capacitor forever (click for simulation): But note that the voltage across this ideal capacitor is continually increasing. Obviously this is not possible in the real world, as something will break down and ... buy motor coupler singaporeWebIf the voltage impressed across a circuit is held constant while the resistance doubles, what change occurs in the current?
