Electronics Engineering

If no current flows through a load, then no energy is received by the load. Energy is transferred through the flow of current, so without any current, there is no energy transfer to the load.

AC/DC is a rock band from Australia formed in 1973. While some original members have passed away, the band continues to perform with surviving members and new additions.

Only if the voltage is the same (12v battery and 12v charge) and there is a lower amperage setting on the charger like around 10, maybe 30 but for small batteries 30 amps is a lot of current and they may get to be too hot warping plates, boiling acid away, and melting the case! 1200 amps... yeah, that's WAY too much. Don't use that setting!

The shape of the magnetic field lines around a straight current-carrying conductor is circular, with the conductor at the center of each circular loop. These magnetic field lines form concentric circles around the conductor, perpendicular to the direction of the current flow.

the skin resistance increases to a large amount because of the sweating

due to stress,

for example-our finger tip become slightly wet when we take stress and its resistance increases

It is not recommended to charge a 6 volt battery with a 12 volt battery charger as it can damage the battery. The higher voltage can overcharge the battery and cause it to overheat. It is important to use the correct charger with the matching voltage to prevent damage to the battery.

The simple answer is NO. Why not use a simple 6 volt power suppy from some junked piece of audio or telephone equipment, Just watch the polatiy when you make your connections.

Using 12V on a 6V battery can fry your battery but not the otherway around.

Variable DC power supplies are commonly used in electronics labs, production lines, and testing environments. They are used to power and test electronic devices such as electrical components, circuits, and sensors. Variable DC power supplies are also used in research and development for prototyping and experimenting with different voltage levels.

When a constant current flows in a long straight wire, the magnetic field lines form circles around the wire.

The direction of the magnetic field may be determined by the "right hand rule." If you position your right hand so the thumb points in the same direction as the current flows, then curling the fingers produces the approximate shape of a circle and the direction that your fingers point is the same direction as the magnetic field lines point in the circles that the field lines form. This is true inside and outside the wire. The field strength gets smaller the further away from the wire that you are and it also gets smaller as you go towards the center of the fire. It is a maximum at the surface of the wire.

Caveat: The above description is exact only for infinitely long wires, but it is also very accurate for long wires where the straight stretch of wire is perhaps a hundred times longer than the wire is wide and no other part of the wire is very close.

A power bar is a type of parallel circuit where multiple outlets are connected to a common power source. This allows multiple electronic devices to be connected and powered simultaneously.

In electrical or electronic circuits, impedance can be said to have capacitive or inductive components. Capacitors cause capacitive impedance, and coils (chokes, transformers, loudspeakers, etc.) cause inductive impedance.

A capacitor is said to be a reactive component in an AC circuit because it holds charge, then releases it, causing a phase shift in the output current. This phase shift in current equates to a phase shift between current and voltage. Reactive power is defined as a phase shift between current and voltage.

An inverter, or inverting amplifier inverts the signal (hence the name). So if you have a sine wave in (start at zero, increase to 100%, then drop back down to zero...), you will get a negative sine wave out (start at zero, decrease to -100%, then increase back to zero...). This is equivalent to saying the input is phase shifted 180 degrees.

Yes, you can charge a 500mA battery with a 1300mA charger. The battery will only draw the amount of current it needs for charging, so it will not be harmed by the higher current output of the charger. However, make sure the charger voltage matches the battery's voltage requirement.

Silver is the best conductor of electricity among common metals. It has the highest electrical conductivity of any metal and is often used in applications where high conductivity is essential, such as in electrical wiring.

Voltage drop is the decrease in electrical potential energy of electrons as they move through a circuit due to resistance. When electrons encounter resistance, they transfer some of their energy to overcome it, resulting in a decrease in voltage along the circuit. This drop in voltage is proportional to the resistance in the circuit and can affect the performance of electrical components.

Yes the circuit needs to have no breaks or have the switch open to let the electrons pass through.

1st is in a.c there is frequency say 50 hz in d.c. it is zero means a.c. produces 50 cycles per second . n d.c. is steady current. 2nd is in a.c inductance comes into picture. but when it is d.c. inductance is zero. 3rd is in a.c skin effect is there. due to this its resistance is high in a.c. as compared to when d.c. current is flowing. 4th is in a.c ,we can quench the arc when fault occurs very easily rather then d.c. current. 5th and major difference is that when we have a.c. quantity we are able to step up or step down the voltages but in d.c. its not possible to get. i hope everybody can understand. bye.

An LED is a diode that emits light; diodes allow current to flow only one direction. The voltage applied to the diode attempts to force current to flow in a specific direction. If the voltage polarity is reversed, and current was flowing before (so there was a small voltage drop across the diode), current will cease to flow (assuming the voltage is not too high for the diode to handle), and (almost) all the voltage will be dropped across the diode (a small leakage current may flow, which means some of the voltage will not be dropped across the diode, but this is in the milli or micro range).

I would never define a diode as a "voltage controller" or "current controller". It could be either or both, from the above description.

When too much current flows through a conductor, it is called an overload. This can lead to overheating and may damage the conductor or the connected equipment if not addressed.

You need basically two things: a complete, closed-loop conductive path and an electro-motive force, that is, a voltage. Check out this picture for a simple circuit containing a battery, two wires, and a light bulb: http://www.bbc.co.uk/schools/ks3bitesize/science/images/sci_dia_52.gif. The wires and bulb complete the conductive path from, and returning to, the battery.

The relative magnitudes of the field in different regions can be determined from an electric field line diagram by looking at the spacing between the field lines. Regions with field lines that are closer together represent stronger electric fields, while regions with field lines that are farther apart represent weaker electric fields. The density of field lines can give an indication of the relative magnitude of the electric field strength.
