A resistor–inductor circuit (RL circuit), or RL filter or RL network, is an electric circuit composed of resistors and inductors driven by a voltage or current source. [1] A first-order RL circuit is composed of one resistor and one inductor, either in series driven by a voltage source or in parallel driven by a current source.
SERI was formed from a merger of the State Secretariat for Education and Research (SER, formerly part of the Federal Department of Home Affairs) and the Federal Office for Professional Education and Technology (OPET, formerly part of the Federal Department of Economic Affairs) on 20 December 2012, and it began its activities on 1 January 2013.
If the four light bulbs are connected in series, the same current flows through all of them and the voltage drop is 3 volts across each bulb, which may not be sufficient to make them glow. If the light bulbs are connected in parallel, the currents through the light bulbs combine to form the current in the battery, while the voltage drop is 12 ...
The series RLC can be analyzed for both transient and steady AC state behavior using the Laplace transform. [16] If the voltage source above produces a waveform with Laplace-transformed V ( s ) (where s is the complex frequency s = σ + jω ), the KVL can be applied in the Laplace domain:
An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter L, and a capacitor, represented by the letter C, connected together.
The Federal Department of Economic Affairs, Education and Research (EAER, German: Eidgenössisches Departement für Wirtschaft, Bildung und Forschung; French: Département fédéral de l'économie, de la formation et de la recherche; Italian: Dipartimento federale dell'economia, della formazione e della ricerca) is one of the seven departments of the federal government of Switzerland, headed ...
Capacitors and inductors as used in electric circuits are not ideal components with only capacitance or inductance.However, they can be treated, to a very good degree of approximation, as being ideal capacitors and inductors in series with a resistance; this resistance is defined as the equivalent series resistance (ESR) [1].
As socialist meetings and press had been banned in Germany, Steinmetz fled to Zurich in 1889 to escape possible arrest. Cornell University Professor Ronald R. Kline, author of Steinmetz: Engineer and Socialist, [14] points to other factors which reinforced Steinmetz's decision to leave his homeland such as financial problems and the prospect of a more harmonious life with his socialist friends ...
