An electric current that is varied to represent information is what?
An electric current that is varied to represent information is called a modulated current. This modulation can take various forms, such as amplitude modulation (AM), frequency modulation (FM), or pulse modulation, and is commonly used in telecommunications to transmit data over long distances efficiently.
What is a electric current that is varied to represent information called?
A variable electric current used to convey information is called a modulated current. Modulation techniques alter certain properties of the current, such as its amplitude, frequency, or phase, to encode data for transmission and processing in communication systems.
What can be done with an electromagnet that cannot be done with a regular permanent magnet?
An electromagnet's magnetic field can be controlled by adjusting the current flowing through it, allowing for dynamic control of the magnet's strength. This flexibility makes electromagnets suitable for applications such as magnetic levitation, electric motors, and electromagnetic cranes, which cannot be achieved with regular permanent magnets.
How do waves carry signals?
Waves can be varied (modulated) by either changing amplitude (amplitude modulation AM) or changing frequency (wavelength) (frequency modulation FM). The modulations are used to carry the information signal.
What is the hypothesis of a rheostat?
The hypothesis of a rheostat is that by changing the resistance in a circuit using the rheostat, the current flowing through the circuit can be varied, thus regulating the output of the circuit.

Why is the letter i used to identify electric current?
The history of electrical study is a long an varied one. Because of this, many conventions used when describing electrical phenomena seem archaic or just plain weird. This particular oddity, using the letter 'I' to represent an electric current is courtesy of Georg Ohm [1] the father of the famous 'Ohm's Law'. Ohm was describing the relationship between resistance, voltage and the Intensity of the electric current [2]. We get the I from intensity. In retrospect, this is ironically fortunate because it saved us from having to later, choose an 'odd' letter to represent Capacitance. [1] Wikipedia: Georg Ohm http://en.wikipedia.org/wiki/Georg_Ohm [2] IEEE History Center: FAQs http://www.ieee.org/web/aboutus/history_center/bitsbytes/faqs.html The origin of "I" is "intensite", the French word for "current", as Ampere was French.
How long does an electric car run?
Not long enough! and not in enough extreme temperatures for Minnesota's varied climate.
What particles move during an electric circuit?
Neutrons. (In type ax1, ay1 is varied due to voltage and amp conditions.)
Where can one purchase an electric radiator?
The places to purchase electric heaters are many and varied. The best place to start would be Amazon. If you are on a tight budget, a good place to try would be eBay.
What is the voltage of a typical electric cell?
Most cylindrical cells supply 1.2 to 1.5 volts, with a varied level of amperage between sizes.
Where can one purchase an electric egg cooker?
The places to purchase an electric egg cooker are many and varied. The best place to start would be Amazon. If you are on a tight budget, a good option to try would be eBay.
What nun wears a blue habit?
The varied colors represent the different orders the nuns come from. These can vary so much even by the shade of blue.
How are the octaves on a keyboard an analogy for the periodic table?
The octaves on a keyboard represent repeating patterns of musical notes, similar to how the periodic table arranges elements based on repeating patterns of chemical properties. Just as notes in an octave have similar but varied frequencies, elements in the periodic table have similar but varied atomic structures that determine their properties. Both systems help organize and understand complex information in a structured way.

What is a device that that produces electric current by rotating a coil of wire in a magnetic field?
A generator or alternator. If the magnetic field is permanent, the current produced from the coil will be alternating current. AC. Alternators usually work the other way round. The magnet is spun inside a coil of wire. The power is taken off from the stator. The rotor is an electromagnet, fed via slip rings on the shaft. The strength of the magnet can be varied and controlled externally, to control the output voltage.
