open circuit is composed of a capacitor with capacitance C and an inductor with inductance L. The capacitor is charged to a voltage V and at time t = 0 the circuit is closed. Find the current as a function of time, I(t).

Energy harvesting is the process by which energy is acquired from existing energy sources. In an energy harvesting project a magnetic field is to be generated using an alternating voltage source. An induction coil is to be placed at a suitable distance from the electromagnet in the magnetic field to power a lightbulb. you are required to design the electromagnet and the harvester induction circuits. For the electromagnetic circuit, you have been supplied with with a sinusoidal voltage source, A current limiting resistor of 50 ohms and a copper rod. For the harvester circuit, you have been supplied with a light bulb and an induction coil. For a lit bulb the maximum allowed current is 0.2 A. When the bulb is on its internal resistance can be considered as a resistor of 15 ohms. The induction coil has a cross-sectional area of 1 cm² and 15 turns of wire. Determine the maximum AC voltage amplitude required in the electromagnet circuit to light the bulb if the induction coil is placed 1 cm…

The illustration shows four capacitors that are connected together in a so-called capacitor bridge. Initially, the capacitors are uncharged. Which relationship must hold between the four capacitances so that the voltage between points c and d remains zero when a voltage U is applied between points a and b?

What is a capacitor and how do they work? What is it about capacitors that make them unique? What is the formula for one time constant? How many time constants does it take to fully charge a capacitor? Show illustrations. What other electronic component(s) are commonly found with a capacitor…especially in timing circuits? What types of capacitors are there? What are the formulas for series and parallel capacitors? If three 30 uF capacitors were connected in parallel what would the net capacity be? How about the net value if the capacitors in Q7 were connected in series? If you were to connect a 5K-ohm resistor in series as in Q7… what would the first time constant be? What about time to full charge? Describe the difference between AC (alternating current) and DC (direct current). Use illustrations. Why is voltage generated and distributed in AC? What type of circuit(s) would change AC to DC? How about DC to AC?
