menuItem1="What is a LED?";
menuComponent1="When current flows through a LED, it lights. The LED has two legs: a short leg called the cathode, which is negative, and longer leg called the anode, which is positive (+). <br><br>In order for a LED to light, a power supply, a component called a resistor and the LED must be connected in <i>series</i>. A series connection looks like three people holding hands in a circle. One person represents the power supply, the other - the resistor and the third the LED. If the LED is connected backwards it will not light. So the plus of the LED must lead back to the plus of the power supply and the minus of the LED must lead back to the minus of the power supply. ";
menuItem2="What is a resistor?";
menuComponent2="If too much current flows through a LED, it blows and if too little, it does not light. A carefully selected resistor ensures just enough current flows through the LED. A resistor also has two legs but the legs do not have polarity i.e. they are neither + nor -.";
