Voltage Dividers

We’ve already looked at resistors and saw how they can impact voltage and current in a circuit.   In those cases, the resistor was placed in series with the other components.  While this is a typical means to deploy a resistor, it isnt the only way they can be used.  In my readings I came…

Electricity and the water analogy explained

If you’ve ever tried to understand amps, voltage, and resistance you’ve no doubt heard the water analogy.  It goes something like this… Consider a tank of water.  The amount of water in the tank is comparable to the amount of electrical charge in a power source.  Now consider the tank has a hole in the…

Measuring voltage and current with a multimeter

While making these measurements likely seem like an obvious task to most – it wasn’t immediately apparent to me how to take these measurements.  Voltage and current are measured in two very different ways.  One of the big stumbling blocks for me was understanding that voltage is always constant in a circuit.  That is –…

Understanding electrical resistance

One of the base level concepts I’ll need to learn more about is resistance.  As you likely know, when talking about the flow of electricity you typically talk about conductors and insulators.  Conductors are materials that allow the free flow of electricity whereas insulators limit or prevent the flow of electricity.  A good example of a conductor…
