Length RT = 40m
Length RS = 16m
Angle S = 120o

i)Apply the sine rule to determine the
angle of the jib to the vertical, i.e.
angle R.

A

a) An instantaneous value of voltage in an AC circuit at time t seconds is given by

v=400sin(50π t – 0.5) volts. Determine:

i) The amplitude, periodic time (s), frequency (Hz) and phase angle

(degrees)

ii) The voltage when t=0

iii) The voltage when t=1s

Engineering Maths. Level 4

b) An instantaneous signal voltage (vs) is described by the equation:

v =340 sin(50πt −0.541) volts

i) Make time (t) the subject of this formula and hence determine the time

when the voltage first reaches 200V.

ii) Sketch one cycle of the waveform
