Why is a MISC meter not recommended for DC measurement?
A. The meter is calibrated for AC and it’s error for DC would be high
B. The meter does not respond to DC signals
C. The error is high due to hysteresis effect

Plz explain the question
P= I^2.R
P= 100*10= 1000
Max error in P= (2*5+5)=15%
so, max error in p = 1000*15%=150 w
plz explain this que
