Do Radios Need Batteries at Alexis Denise blog

Do Radios Need Batteries. A crystal radio doesn't need a battery as it uses the power of the radio waves. When you plug in an ac lead, a switch automatically cuts out the battery power. As such it can only drive a very sensitive earphone and even then it's pretty. What is a batteryless radio? The nearby signal overwhelms everything else by a factor of millions. This radio is either battery or ac powered. There is only one loudspeaker, so this radio can reproduce only mono sounds. Therefore, you don't need a tuner or batteries or anything else. The diode acts as a detector for the am signal as described in the previous section. If you wanted to get really fancy with one, you can use either a half wavelength or a 1/4th wavelength antenna, and use a transistor and battery to amplify the incoming signal. A batteryless radio is a receiver that can operate without a battery providing electrical power. Because you are so close to the transmitter, the antenna is also receiving lots of energy — enough to drive an earphone! Generally, the bigger the loudspeaker the louder the radio (and the better the quality of sound it will make). Batteryless radios don’t require battery power to operate, often using ac mains power instead. Let’s start with the most obvious question:
