Leading zeros are not significant digits, therefore 007 has one.

The purpose of a fuse is to open an electronic circuit when current flow exceeds a certain amount, determined by the rating of the fuse. Opening a circuit under high current conditions can save electronic components from damaged and prevents overheating, which could cause a fire.

when lagging Power Factor changes to leading PF, then the voltage across the circuit in which capacitor bank is connected, is increased.
In the ac waveform of a capacitor the current waveform leads the voltage waveformcurrent is large to start until capacitor fills with it's voltage charge if that helpsAnswerThe terms 'leading' and 'lagging', used when describing power factor, are defined in terms of whether the load current is leading or lagging the supply voltage.In a capacitive circuit, the load current leads the supply voltage, so the power factor is leading.
Capacitor bank is use to control the power factor of the load, because there is many inductive load in the circuit which is the cause of the lagging P.F, so we use the capacitors to maintain the P.F to the unity, the capacitor have the nature of the leading P.F that's way the resultant P.F of the load's lagging and the capacitor's leading current is near to the unity, and the unity P.F has very good effect on the network.
No, no parts of cell phones or mobile phones are made of iron. The metals used in these phones are:Aluminium (covers, frames, battery, circuit board.)Antimony (covers)Barium (circuit board)Beryllium (connectors)Cobalt (lithium-ion batteries)Copper (circuit boards, wires, connectors, batteries)Chromium (cover, case)Gallium (LED light)Gold (electronic parts, connectors, circuit board)Indium (screen)Lead (circuit board)Manganese (circuit board, case)Nickel (battery)Palladium (circuit board)Platinum (circuit board)Ruthenium (circuit board)Silver (circuit board)Iron is heavy, gets warm quickly and reacts with moisture in the air leading to rust, so iron is not a suitable metal for a phone.
there would be no problem with this == == The inductive circuit has a 'lagging' power factor. If you over-compensate with too much capacitive reactance, you could go over the top (past 1.0) , and end up with a leading power factor that may even be numerically worse than when you started. == == == ==
Yes. Typically when a component has two wires and they aren't labeled, it doesn't matter which wire is which.
Because capacitor withdraw leading current from source and net resultant become less lagging.
If there are only a resistor and a capacitor in the circuit, then the phase shift will indeed be between 0 and 90 degrees. When the resistor and capacitor are in series, the phase shift will be negative when the capacitor is connected to a source voltage and the resistor is the load. The phase shift will be positive when the resistor is connected to the source. The lower the values of R and C, the higher the frequency bandwidth.With the resistor and capacitor connected in series and the two parts connected to a current source, the phase shift will be negative. At high frequencies, the output voltages is lower, and the circuit appears as a very low impedance. At low frequencies, the circuit looks more like a resistor. Again, the phase shift will be between 0 and 90 degrees.CommentThe correct term is phase angle, not 'phase shift'. By definition, the phase angle is the angle by which the load current leads or lags the supply voltage. For an RC circuit, the current leads the voltage, so the phase angle is a leading phase angle.
leading the voltage.
Capacitors resist a change in voltage, proportional to capacitance and current. This is called capacitive reactance. As a result, a capacitor in an AC circuit will create a leading phase angle, current relative to voltage. This, for example, can be used to help start a motor by creating two magnetic fields, one leading the other.
Short Circuit
Capacitor banks can improve the power factor if the load is leading, which is unusual. Typically in substations capacitor banks are employed to reduce over voltage.
