1. An aerosol generation device, comprising:
a power supply;
a load that generates heat upon receipt of electric power from the power supply and atomizes an aerosol source using the heat;
a first circuit configured to cause the load to atomize the aerosol source;
a second circuit connected to the first circuit in parallel, and having an electric resistance value higher than an electric resistance value of the first circuit,
wherein the second circuit includes a resistor that is connected in series with the load, wherein the resistor has an electric resistance value higher than an electric resistance value of the load; and
processing circuitry configured to
receive a value of a voltage applied to the second circuit and the load,
compare a value of the voltage applied to the load or the second circuit with a predetermined threshold,
control at least one of a first switch in the first circuit and a second switch in the second circuit based on the comparison,
receive a value of a voltage applied to the load or the resistor wherein the value of the voltage changes according to the changes in a temperature of the load, and
receive the value of the voltage applied to the load.
