Your phone isn't typically on full transmit power in your shirt, this can been by the difference between talk time and standby time on any phone.

Your phone isn't typically on full transmit power in your shirt, this can been by the difference between talk time and standby time on any phone.
- ncmncm 5y agoYour phone emits full transmit power, while in your pocket, in very short bursts. Experiments with E-M effects on biology show that changes in current matter more than steady current. So, the effect of pulses could be larger than if it actually were transmitting full-time. We just don't know.
- SigmundA 5y agoRadiowaves are AC by nature they are not "Steady current". You need to provide at least something backing up this extraordinary claim. Are you claiming a heating effect or something else?
- ncmncm 5y agoIf you believe AC cannot be, at the same time, steady current, you are in for many more surprises. If you think your cell phone antenna picks up signals by some sort of "heating effect", you are in for many more surprises. In fact all varying E-M fields induce electrical currents where they are absorbed. The effects of those electrical currents vary in myriad ways, depending both on the currents and on where they are absorbed. In living matter the currents are carried by motion of ions in solution. Not coincidentally, life is conducted largely by motion of ions in solution.
- SigmundA 5y agoHow is alternating current steady when varies in magnitude? There is no current flowing on a zero crossing, there is a reason AC and radio use RMS current, are you sure you know what your talking about? Incidentally the ADC's that sample the input dissipate the electrical energy captured by the antenna as heat however little it may be as is the case with all electrical circuits that sink electrical energy. So yes your cellphone does use a "heating effect" because where else does the energy go? Do you think it charges the battery or emits light with the captured energy?
- ncmncm 5y agoAll energy, no matter where absorbed, ends up as heat. So, the heat is meaningless to talk about unless you are making popcorn. It is not the heat, at the end, that makes your phone work. You may read up on how antennas work, if you care to have any actual, you know, facts. I promise it won't say one word about heat.
- SigmundA 5y agoNo the ADC use resistors to measure voltage, resistors turn electric energy into thermal energy, they literally use how much time it takes to dissipate electricity as heat to measure voltage. I know someone who needs to read up on antennas and digital receivers and its not me.

- gus_massa 5y ago> they literally use how much time it takes to dissipate electricity as heat to measure voltage. I never heard that, and looking at the list in https://en.wikipedia.org/wiki/Analog-to-digital_converter#Types https://en.wikipedia.org/wiki/Analog-to-digital_converter#Ty... I can't find any that work this way.
