Yes, most of the surge strips have an in-built motherboard.

E.

Joined in parallel, the voltage (or electromotive force, "emf") isn't additive. You'd get four times the current, or four times the life of a single battery, but it would have the same voltage.

No. It depends on the inductive and capacitive reactance of the load.

A shorted motor would read zero ohms. Note, however, that a meg ohm tester is not an appropriate test device to assess if the motor is shorted, because the difference between shorted and "operational" can often be just a few ohms - you need a low resistance test device - not a meg ohm tester.

20000 volts

We know that in a.c frequency changes after 50 sec in the case of 50 hz frequency.

AC or DC voltage, it is the potential difference that counts and also the state of body whether wet or dry which determines the body resistance. It also depends on the insulation of the ground ( an insulator like rubber mat will reduce shock or wearing a boot) Usually DC voltage we encounter is very low voltage of max 50V while AC Voltage is 230V. This could be the reason that electrocution is more in AC than DC. Alternating or Direct potential has no role to play. AC changes so fast ( 50 cycles per second), the fall and rise in potential doesn't has bearing on shock.

you can easily design any circuit of your own choice.

EMF is the voltage across a coil (or motor) due to changes in the magnetic field. If you change the current the coil will generate a voltage (in the opposite direction of the current). So it is not the field but the change that matters.

Because some systems MUST have at least 24 volts to operate and using 28 is a safeguard against potential voltage drop.

XLPE cable has high electric strength,mechanical strength,high-agcing resisting,environmental stress resisting anti-chemical corrossion,and it is simple construction,using convenient and higher operating of long term temperature.It can be laid with no drop restriction.

Various of flame-retandant and non-flame retardant XLPE cable can be manufactured with three technology(peroxide,silance and irradiation crosslinking).The flame-retardant cable covers all kinds of low-smoke low-halogen,low-smoke halogen free,and non-smoke nonhalogenated and three classes of A,B,C.

Some of special XLPE cable can be manufactured according to ther other standards required by customs.

XLPE cable having higher long-term working temperature and greater current rating,at the same environment XLPE cable may be reduced size(nominal cross-section)1 or 2 class in comparison with paper

conventional current flow

Answer: Hair dryers are made not to damage your hair because they do not get that hot. You should sit under the dryer until you feel your hair is dry depending on how long or short your hair is you have to make that decision yourself. So don't worry about how long you have to sit under it. It will be safe enough.

0n3 .. that's O scale (1:48) running on .75 in gauge track (1:48 = 1/4" = 1ft.) ... On30 runs on HO track (meaning that HO track represents 30" track in O scale)

It should me stamped on the information plate.

If this is not on it, then there will be the running current stamped on the plate. Multiply this by the supply voltage to find the power in watts. Take the horsepower of the motor and multiply it by 746. There are 746 watts in 1 HP. It is also the same for single phase motors.

If you are defining electrical pressure as voltage then the answer to your question is yes. W = A x V.

electronics engineering is the branch of engineering which deals with the flow of current in a semiconductor devices/components.

Semiconductor devices/components are those element which made from semiconductors like silicon germanium GaAs and other material.

they are widely using in current generation.

copper losses are power losses due to flow of current in the wires or resistances,if the resistance is R, current is I then copper losses are I2R.

for a 3-phase system; copper losses are same but for a single line, total losses are 3I2R.

A RC circuit is a simple filtering circuit. The impedance of R will stay the same across the frequency band. The impedance of C will vary according to 1/jwC (j = i = imaginary number, w = omega/frequency in radians, C = capacitance in Farads). As frequency varies from low frequency to high frequency, an increasingly smaller amount of the signal voltage will "drop" across the capacitor. This is known as a first order (one reactive element, the capacitor) low pass filter if the desired signal is measured across the capacitor. If measured across the resistor, this would be a first order high pass filter.

Edit: if you are talking about ESR (equivalent serires resistance), it is a parasitic component inside a capacitor. Theoretically, you don't want it but it's there.

Current is proportional to the potential difference and inversely proportional to resistance.

Ohm's law: Current equals voltage divided by resistance

shunt field winding have more resistance than series field winding
