When there is a power outage and the neighborhood loses electricity, I noticed a lot of car alarms go off. Why does that happen?
In: Engineering
I’ve never heard of car alarms going off when the power goes out.
They’re not connected, there’s no sensor in the car to detect nearby electricity. Power going out nearby isn’t going to trigger a car alarm.
What I *have* seen happen is lightning strikes, which blows a transformer or something that causes an outage. Then, the thunder from the lightning resonates at a frequency that triggers car alarms.
Was there a thunderstorm when you saw this happen?
