It would align itself with the magnetic North and South poles of the Earth.

there are two types:- 1) simple diode detector 2) practical diode detector the diode is common device used in am demodulator. signal(am demodulator signal ) is applied anode and output is taken from cathod

We will have less energy in the future because of global warming today global warming will get worse over the years and probablys in maybe 200-300 years the UK may not have energy left so everyone will die without power cause u need some power to cook food to live on or u can eat raw but its not good for you u will probz get food poisoning

the British isles will have too many people living on it and a failing infrastructure.( transmission lines)

Closed-circuit television (CCTV) is the use of television cameras to transmit a signal to a specific, limited set of monitors. It differs from broadcast television in that all components are directly linked, and that the signal is not openly transmitted, though it may employ point to point wireless links. CCTV is often used for surveillance in areas where there is an increased need for security, such as banks, casinos, and airports. They may also have military uses. The use of CCTVs in public places has increased, causing debate over security versus privacy. CCTV was developed as a means of increasing security in banks. Today it has developed to the point where it is simple and inexpensive enough to be used in home security systems, and for surveillance.

You could have a bad blower motor or there is a resistor inside the blower motor housing which is located under the glove box on passenger side of car (where your feet would go) That could be your problem.

You need to divide the supply voltage by the impedance of the load. The impedance of the load is the vectorial sum of its resistance and reactance, where reactance is proportional to frequency.

Output power can never be more than input power. With a transformer, it is possible to increase the output current (while decreasing the output voltage), or to decrease the output current (while increasing the output voltage).

Switches, fuses and circuit breakers are examples of some of the electrical parts which can connect or disconnect a circuit to a source of current.

A diode does it for alternating current, but only for one half of each cycle.

"Connecting" allows an electric current to flow through the circuit. "Disconnecting" stops an electric current from flowing through the circuit.

This is copied from Section 6.11, Question 8 in "Modern Refrigeration and Air Conditioning." The answer is (B), "The open circuit prevents flow. The open AEV allows flow to occur." Although a bit obscure, the answer is correct because, within the context of an electrical circuit, an "open circuit" (i.e. disconnected wire) would prevent the flow of electrical current. Within the context of a refrigeration circuit, an open AEV (automatic expansion valve) would permit the flow of refrigerant into an evaporator coil to provide cooling.

there is no specification of Dy11.. it will be Dyn11.. it is the vector group of the transformer. capital d means primary winding is delta secondary winding is star(y) and the secondary current lags voltage by 30degree this angle when shown in clock will be looking like 11 o clock

You can increase the current. It depends on how you add them, though: that is, how they are connected to each other.

It is used to couple output of one stage to input of next stage

If resistance is high that time the current flow is low. Bcoz current always flow through the low resistance path.

armoured OD X 10 time and gain lay of armouring.

A closed series circuit is one where the current flows through all devices in the circuit. Opening a switch prevents current from flowing in the circuit and it becomes simply an "open circuit". Any device that operates with current (light, LED, motor, etc) will no longer function.

connect 2 2ohm resistors in parallel and connect it to a series 2ohm resistor

In a properly designed and installed system, nothing will happen. If you press the start first the contactor or start relays may close energizing the motor briefly but the relay will open and stay open when the stop is pressed.

with some of the very best transformers about 7kva

with the ones made recently and costing 1/2 or 1/3 as much perhaps 25Kva

Is this a trick question? It could be. Let's look at AC and DC and see what's up. We'll start with DC. DC is direct current. The voltage of "regular" DC is a fixed value. Like in a car, the battery is about 12 volts. (It's actually a bit higher, but work with me here.) It's a nice, constant 12 volts all the time. The headlights experience a constant 12 volts when they are on. What about AC? Alternating current, or AC, is based on a voltage source that has a changing polarity. For a while it's one way, and then for a while it's the reverse. Also, the voltage isn't constant and then suddenly changing polarity. If we look at the voltage on an AC line, at a certain instant, the voltage is zero. It then rises up over a short time to some maximum value and then decreases to zero again. Then the polarity changes and the voltage goes to some maximum negative value before returning to zero. We usually think of a sine wave, and that's pretty correct. This is how the voltage is actually generated in a generator. It spins, and the voltage output follows a sine wave. Cool so far? Good. Let's jump. With the AC voltage rising to some maximum value, what is that maximum? And since it rises to the value over a short period of time rather than just jumping straight up there, don't we have to "average out" the voltage over the time it takes for it to get to the maximum? And then "average it out" for the back half of that change as it decreases to zero? Yes, we do. And what we end up with is an "effective" voltage, or a "DC equivalent" voltage. In U.S. houses, the 120 volts AC (again, work with me here) is actually the DC equivalent voltage of the AC sine wave. The sine wave actually has a peak at about 170 volts. We could say that a given sine wave has a peak voltage of 170 volts. Or, since it goes negative as much as it goes positive, the total voltage change from the positive peak to the negative peak is twice the peak voltage, or 340 volts peak to peak. But we like to use the "average" or (mathematically) the root mean square voltage, which is the DC equivalent voltage to measure AC. So if an incandescent reading lamp on an end table in a house is plugged into a 120 volt wall outlet, it will have the same brightness as if the lamp was hooked up to a 120 volt DC battery. The effective voltages will be the same because the AC voltage is actually based on the DC equivalent voltage.

The circuit breaker for the headlights is intergrated with the headlight switch.
