A percentage or numbered setting that cycles the magnetron.
Also known as: Microwave power setting, Defrost power level
A microwave's power levels do not reduce the strength of the microwaves. The magnetron runs at full power and is switched on and off, so half power means on for half the time — which is why a low setting is genuinely gentler only because of the resting intervals.
Sets the proportion of time the magnetron runs, expressed as a percentage or a numbered level.
Contexts: Electrical equipment
Cycles full power on and off rather than reducing the output, so heat spreads through the food during the off intervals rather than the microwaves being weaker.
