198. What maximum voltage can be applied across the capacitor for very short period of time?

The voltage across a 5 μF capacitor is known to be Vfort≥0 , where t is in seconds.

Part B

Find the power at the terminals of the capacitor when t = 185 μs .

Part D

Find the energy stored in the capacitor at t = 185 μs

Part E

Find the time when the maximum energy stored in the capacitor occurs.

Part F

Find the maximum energy stored in the capacitor

Solve and Find:
a) The complex power absorbed in the voltage source.
b) The real power absorbed in the capacitor.
c) The reactive power absorbed in the resistor in series with the -j800 capacitor.

The following three impedances are connected in series across a 40 V, 20 kHz supply: a 
resistance of 8 Ω, a coil of inductance 130 μH and 5 Ω resistance, and a 10 Ω resistor in 
series with a 0.25 µF capacitor. Sketch a neat diagram representing this network, and 
calculate:
5.1.1 The inductive and capacitive reactance’s. (4)
5.1.2 The magnitude and phase angle of the circuit impedance. (4)
5.1.3 The voltage drops across resistance, inductance and capacitance.
