I could use Q=Ixt right?PietKuip said:Use the GUESS method: Given, Unknown, try to find an Equation that kind of fits the given and unknown quantities (or just multiply every given number), Substitute the numerical values, "Solve".
(None of this requires any insight in the physics, of course. It is just a way of getting through schools with this kind of teaching.)
Is Q energy, or something else?Sace Ver said:I could use Q=Ixt right?
Yes, the charge Q is proportional to current and duration, but there is no build-up of charge in a radio, it is not very relevant in this context.Sace Ver said:I could use Q=Ixt right?
Okay first I would use Q=Ixt and then I would use E=VQ.SteamKing said:Is Q energy, or something else?
What's the definition of electric current?
And that would be the right answer!Sace Ver said:Okay first I would use Q=Ixt and then I would use E=VQ.
The energy transferred in radio refers to the amount of electrical energy that is converted into electromagnetic waves and transmitted through the air or space to carry information.
Energy is transferred in radio through the use of an antenna, which converts the electrical energy into electromagnetic waves. These waves then travel through the air or space until they are received by another antenna, where they are converted back into electrical energy.
The amount of energy transferred in radio can be affected by various factors such as the distance between the transmitter and receiver, the power of the transmitter, and the type and quality of the antenna used.
The energy transferred in radio is measured in units of power, such as watts or kilowatts. This measurement is typically taken at the transmitter and can vary depending on the strength and efficiency of the transmission.
Energy transferred in radio is used in many practical applications such as radio broadcasting, cellular communication, WiFi, and satellite communication. It is also used in radar systems for navigation and in medical imaging technology such as MRI machines.
