A current waveform may be described by… is = 13 cos (2πft − π/ 4 ) [A] where frequency, f = 1Hz and t represents time. Make time (t) the subject of this formula and hence determine a point in time when the current waveform has a magnitude of +10A
2,
The instantaneous value of a power signal may be described by; 12∠ ( 3π/ 8 ) [W] Find the magnitude of the vertical and horizontal components of this signal. Note that the symbol ∠ indicates ‘angle’.
PLEASE HELP WAY ITS OVER MY HEAD
