Electricity and Electronics
Lesson 1 of 1
  1. 1
    Introduction
    Before diving into building electric circuits, lighting up LEDs, and creating food-serving robots, we must first understand the basics. So, what exactly is electricity? Electricity is the flow of…

    Electronic Circuits
    An electronic circuit is a path for transmitting electric current supplied by an electric source. In order for a path to be a circuit, it must start and end at the source. The very name “circuit”…

    Voltage
    Voltage is the amount of electrical potential energy between two points. It’s measured in Volts and represents the force that sends the electrons through a circuit’s conductive path and load. …

    Current
    When we talk about the flow of electricity, we are specifically referring to current. Current is the rate at which electrons flow through a circuit. With a voltage applied to a circuit, the c…

  5. 5
    Resistance
    We now understand that the driving force within a circuit is voltage, and the flow of electrons through a circuit is current. We will now look at the opposition of current within a circuit known as…

    Ohm's Law
    Electronic circuits involve the manipulation of voltages, currents, and resistances. Knowing how these three properties relate to each other is a foundational part of circuit design. These relation…

    Light-Emitting Diodes
    Light-Emitting Diodes are circuit components that turn electricity into light. They are a type of diode, which is a circuit component that only lets current flow in one direction. Also known a…

    Creating an LED circuit
    In a previous exercise, we applied Ohm’s law using a circuit with a single resistor as the load. In this lesson, we will look at a load that consists of two components: a resistor and an LED. ![Ci…
