Amplitude of current (I) can be calculated using the formula I = C * dU/dt, where C is the capacitance and dU/dt is the derivative of voltage with respect to time.
Given that C = 6uF and U = 50cos(110^3t), the derivative of U with respect to t is dU/dt = -5010^3sin(1*10^3t).
Plugging in the values, we get:
I = 6 (-5010^3sin(110^3t)) I = -30010^3sin(110^3t) I = -300sin(110^3t)
