Preparing to study electrical engineering on Khan Academy Basic electrical quantities: current, voltage, power Numbers in electrical engineering Defining the standard electrical units

We will create our first mental models for these basic electrical quantities. We will also talk about power, which is what happens when voltage and current act together.

Review the components of a circuit and their symbols such as battery, resistor, and switch. Analyze how the power of a resistor is related to the current and electric potential difference …

We can't imagine our lives without electricity. But what exactly is electricity? How does electricity light up our houses? What does a battery do? What is the cost of electricity? We will answer …

Circuit analysis is the process of finding all the currents and voltages in a network of connected components. We look at the basic elements used to build circuits, and find out what happens …

Video transcript - [Voiceover] All right, now we're gonna talk about the idea of an electric current. The story about currents starts with the idea of charge. We've learned that we have two kinds …

TG Science Class 7 Course: TG Science Class 7 > Unit 7 Lesson 2: Symbols of electric components Symbols of electric components Basics of electrical Components Basics of …

We present the basic concepts for continuous-time and discrete-time signals in the time and frequency domains. Time and frequency are related by the Fourier transform.
