why can 't we measure a.c by an ordinary ammeter ?

Answers

Answered by sahithi3

We cant measure because ac is in the form of sin and cos values where as dc can be measured in an ordinary ammeter

Answered by merajtahseen

Generally ordinary ammeter consists of PMMC (Permanent magnet moving coil ) instruments which can measure dc values only. For ac values we use digital instruments. Hope my answer clear your doubt...
