To achieve this it has very low resistance in one direction to allow current flow and high resistance in the other direction to impede current flow. This feature of diodes is clearly represented in the generic diode circuit symbol:</p><p><img src="/static/diode.png" /></p><p>An LED diode lights up when the right amount of current flows through it. A standard LED has a maximum current of 20mA. An appropriate <a href="Resistance.md#resistors">resistor</a> must therefore be added to the circuit to ensure the current doesn’t exceed this amount.</p></div></article><nav class="ui attached segment deemphasized bottomPane" id="neuron-tags-pane"><div><span class="ui basic label zettel-tag" title="Tag">electronics</span></div></nav><nav class="ui bottom attached icon compact inverted menu blue" id="neuron-nav-bar"><!--replace-start-9--><!--replace-end-9--><a class="right item" href="impulse.html" title="Open Impulse"><i class="wave square icon"></i></a></nav></div></div><!--replace-end-6--><!--replace-end-3--><!--replace-end-2--><div class="ui center aligned container footer-version"><div class="ui tiny image"><a href="https://neuron.zettel.page"><img alt="logo" src="https://raw.githubusercontent.com/srid/neuron/master/assets/neuron.svg" title="Generated by Neuron 1.9.35.3" /></a></div></div></div></body></html> |
