dielectric
/ˌdaɪ.ɪˈlɛk.trɪk/
Definition
A non-conducting material used in electronic components like capacitors that can support an internal electric field while minimizing energy loss.
Etymology
The word is derived from the Greek prefix 'dia-' (through) and 'electric'. It was coined to describe a substance that acts as an insulator through which electric force can be transmitted.
