Can a 9 volt battery generate enough current through Nichrome wire to heat it up?
My son is trying to create a battery powered electric blanket using one or two 9 volt batteries with some Nichrome wire. Will he be able to generate enough current to cause the Nichrome wire to heat up properly? He would appreciate any tips on what wire length he needs or what other options he has for a voltage source. He really wants to make it using a battery.
