The term carries a formal tone, reflecting its roots in physics and electrical engineering.

Common mistake
Learners might confuse this with general sparks, known as 火花, which are smaller and less sustained. An electric arc implies a continuous, high-energy discharge through a gas, whereas a spark is typically a transient event.
