- 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…1. A purely resistive circuit the current is leading by 90° with respect to voltage. 2. A purely inductive circuit the current is lag behind the voltage by 90°. 3. A purely capacitive circuit the current is lead by 90° with respect to the voltage. 4. A capacitor element stored magnetic energy. 5. An inductor element stored electrical energy. 6. Resistor elements consume power. 7. Angle between current and voltage is called power. 8. The power factor angle for a purely resistive is zero. 9. The power factor angle for a purely inductive load is -90°. 10.
