Is there even any validity at all that cables close to the body/head? Nor do can you absorb any power from a heating pad other than the radiated infrared heat which is therapeutic and heat like sunlight is much more than trillion ( really ) times higher frequency than 50/60 Hz. You do not absorb any measureable power by proximity to an extension cord whether it is conducting 50 Amps or 0 Amps. The extension cord is designed to carry up to that many volts and amps safely without being damaged. No, the rating on the extension cord is a maximum rating. Is more going through because of the high amperage and wattage? (This is approximate, since there may be slight manufacturing variations and your actual power line voltage might not be exactly 120) For example, a 60 watt bulb should use about half an amp. Take the lamp's wattage and divide by 120 (the voltage). Since I read in my bed around an hour every day, I was also wondering, when the lamp is on, how much current is going through the cable? If you want to avoid that you have to disconnect it at the wall socket end.Īlso, the extension cord that I bought is 125V, 15A, 1875W. There will still be normal mains voltage (120 volts AC) in the cable regardless of whether anything is turned on. ![]() billionths of amps) due to the cable's capacitance. There will still be a very small amount (some nano-amps i.e. There will be negligible current flowing through the cable. ![]() However, is there current/electricity still going through the cable when the switch is turned off?
