In a.c. the current keepsanswer
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. 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.

WebThe Current Transformer ( C.T. ), is a type of “instrument transformer” that is designed to produce an alternating current in its secondary winding which is proportional to the current being measured in its primary.Current transformers reduce high voltage currents to a much lower value and provide a convenient way of safely monitoring the actual electrical … WebThe answer: chemical energy did work to make them separate. The amount of work is the very definition of voltage: Voltage = energy required / amount of charge = Joules / Coulomb As the chemical energy is depleted so follows the voltage.

The simplest way to build an active AC constant-current source takes only 4 parts: A suitably rated bridge rectifier (600PIV, 1A works) A suitable resistor (you'll have to try several values) A HV depletion … 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.
