In a.c. the current keepsanswer
WebWhen an alternating voltage is applied across a capacitor, the current leads the voltage by a phase angle of 90 degrees. This means the current oscillates a quarter of the cycle ahead … 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

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 … 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.
WebThe RC circuit includes an AC generator, a resistor and a capacitor. A capacitor is fundamentally a group of conducting plates divided by an insulator. Thus, a stable current … WebSep 12, 2024 · An ac generator produces an emf of amplitude 10 V at a frequency \(f = 60 \, Hz\). Determine the voltages across and the currents through the circuit elements when …

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.
WebDC circuits the product of the current and voltage gives the power. It is convenient to use a similar formula for the average power dissipated in AC circuits when the current and voltage are in phase. However, the product of the raw voltage and current amplitudes (the zero-to-peak voltages and zero-to-peak currents), is twice the actual average ...
WebFind the AC RMS values of a current that produces a maximum voltage of 250V and a maximum current of 5A. Solution We use the equations given for AC RMS values and plug in the maximum voltage and current values.
