Kirchhoff's Voltage Law says if you travel around any loop in a circuit, the voltages across the elements add up to zero.

Explore the voltage divider, a fundamental circuit pattern in electrical engineering, consisting of two series resistors that control output voltage. Master the voltage divider expression, which calculates …

El voltaje de salida es una fracción fija del voltaje de entrada. Dos resistores definen la razón.

It's called a voltage-dependent voltage source. And it's the same as a regular ideal voltage source except for one thing, it says that the V, in this case V out, equals gain times V plus minus V minus.

Ups. Algo salió mal. Por favor inténtalo otra vez. Oh no, parece que encontramos un error. Necesitas actualiza. Si este problema persiste, avísanos.

Let's learn how to calculate current and voltage across each resistor in a circuit.

Summary: Our voltage divider takes an input voltage (in this case 12 V , but it could be any value) and scales it down to create an output voltage that's 3 / 4 of the input voltage. The 3 / 4 ratio is …

Analyzing electric potential difference across a resistor using Ohm’s law If the current encounters resistance, the electric potential difference decreases according to Ohm’s law. We sometimes call …
