DC Circuit and electrical power review (article) | Khan Academy
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 …
Symbols of electric components (article) | Khan Academy
A picture of a circuit drawn with symbols is called a circuit diagram. In a closed (ON) circuit, current flows continuously from the battery’s positive terminal back to its negative terminal …
Circuit components and types of circuit (article) | Khan Academy
Let's review the components of a circuit and their symbols such as battery, resistor, and switch.
Circuit terminology (article) | Khan Academy
We are developing methods for analyzing a circuit. So far we've defined the most common components (resistor, capacitor, and inductor) and sources (voltage and current). Now we …
Sign convention for passive components and sources - Khan …
Using this third convention means the current from a voltage source or battery will almost always end up with a positive sign. The exception is a rechargeable battery while it is being charged. …
Analyzing a resistor circuit with two batteries - Khan Academy
Discover how to solve complex circuit problems in physics by simplifying schematics, combining parallel resistors, and applying Ohm's law. Master the art of analyzing circuits with multiple …
Ideal elements and sources (article) | Khan Academy
The symbol on the left is used for a battery. The longer horizontal line on the battery symbol represents the positive terminal of the battery, and the shorter horizontal line represents the …
Node voltage method (article) | Khan Academy
We say the voltage source is floating. A floating source is a problem for the Node Voltage Method, but it is not too big of a challenge. In this circuit, battery V 2 is floating. Let's use the Node …
DC Ammeters and voltmeters review (article) | Khan Academy
Review the key terms and skills related to voltmeters and ammeters, including where to place them in a circuit.
Ideal sources (video) | Circuit elements | Khan Academy
The convention for the polarity of a battery symbol is the long line there is the plus terminal and the short line right there, that guy is the minus terminal. So that's the convention for a battery.
