Joule Thief - solar garden light | All About Circuits

23/10/2012· A solar garden light uses a 400mAh or 600mAh Ni-Cad battery cell and a real ferrite core inductor. It lights the LED at night for about 8 hours following a sunny day in summer. The solar panel is too small to fully charge a rechargeable cell with a capacity more than 600mAh so half of your 1300mAh cell will be wasted.

Kirchhoff's rules | physics | Britannica

Kirchhoff’s rules, two statements about multi-loop electric circuits that embody the laws of conservation of electric charge and energy and that are used to determine the value of the electric current in each branch of the circuit. The first rule, the junction theorem, states that the sum of the

Circuit Construction Kit: DC - PhET

Experiment with an electronics kit! Build circuits with batteries, resistors, ideal and non-Ohmic light bulbs, fuses, and switches. Determine if everyday objects are conductors or insulators, and take measurements with an ammeter and voltmeter. View the circuit as a schematic diagram, or switch to a lifelike view.

Electrical impedance - Wikipedia

In electrical engineering, electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied.. Quantitatively, the impedance of a two-terminal circuit element is the ratio of the complex representation of the sinusoidal voltage between its terminals, to the complex representation of the current flowing through it.

Joule Thief Single Cell LED Driver

The LED duty cycle is 368 us / (368 + 672) or 35% and the average current is about 37 ma for an overall average current of about 13 ma. When the LED is driven directly from the power supply at 13 ma DC the brightness is about the same as from the Joule Thief circuit with 1.0 V P.S. Vled. Iled. 2.89.
