Resistance Measurement
We talked a lot about voltage dividers and resistance, but how can we actually measure resistance?
Potentiometers are a common example for voltage dividers. Let's have a look at how they work and how they can be used.
Voltage Dividers
As we are now familiar with resistor combinations, let's take a deeper look into voltage dividers.
Resistor Combinations
We already know how resistance, current and voltage behave for single resistors. But what about more complex resistor combinations?
Ohm's Law
When talking about resistance, we cannot avoid ohm’s law, which shows the connection between current, voltage and resistance.
Conductivity and Resistance
Among the components found in circuits, resistors are pretty common. Let's take a look at them and the conductivity of different materials.
Using a DMM
A multimeter is an indispensable tool when analyzing electronic circuits. Let's discover how to use it!
Electricity Fundamentals
Before we start the circuit basics series, let's first take a look at the fundamentals and the history of electricity.
