DC Circuits This topic covers “DC Circuits” of A Level Physics. (Equivalent to Advanced Placement) If this is too advanced for you, you can try the more basic versionhere. Sub-Topics: Kirchhoff’s First Law Kirchhoff’s Second Law
The concept of electric circuits is the basis for our use of electricity.One nice feature of an electric circuit is that you can install a switch in the circuit to turn the power on or off when you want.Note: Although DC electric current is designated as going from positive (+) to the...
1AdvancedPhysics-Electric Circuits, DCCircuits are classified by the type of path that the electricity follows as it goes around the circuit.There are two types of circuits-series circuits and parallel circuits. In a series circuit there isonly one path. All the circuit components are in line,...

The principle of voltage being the same across all parallel-connected components is (also) an expression of a more fundamental law of physics: the Conservation of Energy, in this case the conservation of specific potential energy which is the definition of voltage. In order for voltage to differ...
AP Physics C DC Circuits Resistors in Series What is constant? What ‘adds up’? How do you determine the equivalent resistance? Sample Problem #1 The current flowing in a circuit containing four resistors connected in series is I = 1.0 A. The potential drops across the first, second and ...
Linear Circuit Definition and Limitations Before we dive into Thevenin’s theorem, let’s discuss the limitations when applying Thevenin’s theorem to linear circuits. In a linear circuit, all the underlying equations must be linear (no exponents or roots). The restriction of Thevenin’s theorem ...
34K Electricity is produced when an electric current runs through a circuit. Learn about the discovery and different types of electricity, and explore the definition and role of electric current in series and parallel circuits. Related to this Question ...

As their name suggests, true inverters use what are called toroidal (donut-shaped) transformers and electronic circuits to transform direct current into a smoothly varying alternating current very similar to the kind of genuine sine wave normally supplied to our homes. They can be used to power ...
