q (1010e2") mC, find the current at 1 = 1.0 s.
Answer: 2.707 mA.

4.1 The current in an ac circuit at any time 𝑡 seconds is given by: 𝑖(𝑡) = 120 sin(100𝜋𝑡 +
0.36) amperes. Determine:
4.1.1 The peak value, the periodic time, the frequency and phase angle relative to
120 sin(100𝜋𝑡). 
4.1.2 The value of the current when 𝑡 = 0. 
4.1.3 The time when the current first reaches 60 A. 
4.1.4 The time when the current is first at maximum. 

16. The current is ____________ times the maximum current at half-power points of a resonance curve.

40. The voltage lags the current by cycle in a
