There is less resistance in the high beam lamp filament.

Work Step by Step

$Electric \; power = (current) \times (voltage)$. This is discussed on page 440. More power for the same battery voltage means that the current is greater. By Ohm’s law, more current for the same battery voltage means that the high beam filament has less electrical resistance.
