How much current flows in a 12 watt radio connected to 120 volt circuit?
A 120V household electrical outlet supplies 12 watts of powerwhen the current is 0.1 Ampere (and the power factor is 100%).
What is the wave source of a radio wave?
The source is the RF current in the transmitting antenna.
How do you build an AM radio?
The construction of an AM radio generally consists of a germanium diode crystal along with an electro magnet. In order to receive different currents, the crystal is responsible for the changing frequencies. Therefore, in order to change the frequencies, there must be something in control of the crystal. That is where the electro magnet-- an iron rod wrapped around with catshair wire connected to a power source such as a battery-- fits the job. Although the electro magnet is usually connected to a battery, it can actually use the power of the current that flows through the crystal as it takes in the energy supply of the radio waves. All that you need left is a tiny earphone that slightly contacts the surface of the germanium diode crystal.Note: there is no harm of the radio waves that travel through your mini radio (you may be mistaken by radioactivity)

Why does your radio shack light emitting diode stop blinking after 15 seconds?
A: Check your supply volatge and current . I suggest you have too mauch current
How much current flows in a 12-watt radio connected to a 120-volt circuit?
Since power = current x voltage, you would divide the power (watts) by the voltage. The answer would be 1/10 amps or .10 amps.
How do you produce electricity from electromagnetic waves?
Current flows through any conductor when electromagnetic waves fly past it. That's how a radio antenna works.
Is alternating current a mechanical or em wave?
Alternating current is a flowing of electricity that changes its polarity (the direction it flows) regularly. EM occurs from AC when the electricity flows in a coil. Substantial EM radiation can also result from AC in a straight wire ... the principle of a radio transmitting antenna.
Can you use a cb radio with a 12 volt regulated 5 amp power supply?
Yes, you can use a CB radio with a 12 volt regulated 5 amp power supply as long as it meets the voltage and current requirements of the radio. Make sure the power supply can handle the CB radio's power consumption to avoid damaging the equipment. Additionally, ensure that the power supply is of good quality and can provide stable power output to prevent any interference with the radio signal.
How can you power a 12V car radio from a 110V wall outlet?
You will have to purchase a power supply with a 12 volt DC output capable of handling the current draw of the car radio. Try "google" to find the manufacturer's specification sheet for the radio. In the specs. will be the amp draw of the radio. With this information you will know what amperage the output of the power supply needs to be.
Can you connect a radio to a light switch?
If you mean can you plug a radio into an outlet controlled by a light switch, the answer is yes, provided the radio does not draw more current that the circuit can supply. (This would not apply to your standard household radio, but only to a high powered unit.)
How much current flows into a 12 watt radio connected to a 120 volt circut?
It is a tricky question since it depends on what the 12 watts refers to. It could be the peak input power the radio uses in normal operation. Or it could refer to the audio output power rating at some volume (usually half). If it is the input power, it might use more current when first turned on, the "inrush" current, or more when the volume is louder. The simplest answer is use the formula watts = volts x amps. But the simplest answer is not always the best.
