Although circuit analysis is typically used to analyze what a circuit is doing, you can also use circuit analysis to design a circuit to perform a particular function. Knowing how to analyze circuits allows you to add the basic applications of rlc circuit elements to a circuit during the design phase so that the circuit performs the way you want it to.

Here are ten of practical applications for circuits. Dimmer switches are actually adjustable voltage dividers referred to as potentiometers in the electrical engineering world. From a circuit analysis perspective, you can model a potentiometer as two resistors connected in series. The connection or junction point between the two resistors is where the wiper arm is located to vary the resistance.

By varying the amount of resistance, you vary the amount of voltage. In the case of dimmer switches, this variance allows you to adjust the lighting in a room. The Leyden jar, a simple capacitor, consists of one piece of metal foil coating the basic applications of rlc circuit of a glass jar and another piece of metal foil coating the outside. The jar serves as the dielectric insulator between the two conducting foils.

The Leyden jar holds electricity where energy is stored within the glass. To talk to the real world, a computer needs digital-to-analog converters. You can use an operational amplifier op amp with multiple inputs to feed an inverting summer using an op amp. To reduce the number of resistors using an inverting summer, you use an R-2R network.

Only two resistor values are needed in an R-2R network for any number of digital inputs. A two-speaker system has one speaker called a tweeter that handles high-frequency music and another speaker called the woofer that handles the low frequencies.

The input audio signal feeds across the series connection of a capacitor and resistor. The resistor terminals feed the input of the tweeter, and the capacitor terminals feed the woofer. To analyze a two-speaker system from a frequency perspective, you need to know about high-pass and low-pass filters. Say you want to show that a light emitting diode LED is turned on.

You need to limit the current going through the LED; otherwise, you may destroy it with too much current.

To limit the current, you connect resistors to limit the current or voltage of the diode. Circuit analysis helps you determine how much resistance you need to protect the diode. You can take a physical variable such as temperature range and convert it to a voltage range. For example, suppose you need an amplifier to pump up a weak signal from a temperature transducer.

A transducer converts a physical variable to an electrical variable, basic applications of rlc circuit. The other input is a constant voltage source that moves the signal up and down the desired voltage range via a potentiometer variable resistor. The Wheatstone Bridge is a circuit used to measure unknown resistances. Mechanical and civil engineers measure resistances of strain gauges to find the stress and strain in machines and buildings.

The bridge network has three precision resistors basic applications of rlc circuit one unknown resistor, basic applications of rlc circuit. Two of the known resistors are potentiometers, which are adjusted to balance the bridge network and thus determine the unknown resistor. The accelerometer uses a Wheatstone Bridge arrangement of strain gauges. You can use an array of strain gauges to develop accelerometers. A common strain gauge consists of a flexible backing that supports a metallic foil pattern.

The strain gauge leverages the changes of its physical dimensions when mechanical force acts on the strain gauge. Suppose that inside a rocket, you have a miniaturized cantilever beam with a mass hanging at one end, basic applications of rlc circuit. The strain gauges on top stretch from the upward acceleration, resulting in an increase in resistance; meanwhile, the strain gauges at the bottom get compressed, decreasing the resistance of the basic applications of rlc circuit gage, basic applications of rlc circuit.

Because of the difference of resistances in the strain gauges, you can use voltage divider arrangements and a bridge network called a Wheatstone Bridge to determine the amount of acceleration. You can modify the Wheatstone Bridge by replacing two of the four resistors with two capacitors and setting the other known resistors equal.

You have two resistor-capacitor RC series branches connected in parallel fed by an AC source. You take each point between the RC series combination and feed it to an audio differential amplifier connected to a beeper.

The capacitances between the metal plates vary as the plates pass over the stud. The capacitors are equal when the stud finder is centered on the stud, and the Wheatstone Bridge is said to be balanced. When the stud is off-center, the capacitors are unequal and a sound is emitted.

The timer basic applications of rlc circuit is an integrated circuit. You can use an external resistor and capacitor network to change the timing interval by the careful choice of resistors and capacitors.

You can configure the chip to work like a cooking timer a one shot. After you set the timer and a certain amount of time elapses, the timer goes off. Or you can configure the chip as a two-state clock astabletriggering a series of pulses at regular intervals.

Here are ten of practical applications for circuits. Potentiometers Dimmer switches are actually adjustable voltage dividers referred to as potentiometers in the electrical engineering world. As the admittance, Y of a parallel RLC circuit is a complex quantity, the admittance corresponding to the general form of impedance Z = R + jX for series circuits will be written as Y = G - jB for parallel circuits where the real part G is the conductance and the imaginary part . Answer Wiki. You’ll study the building blocks of circuits. Then what you’re learning now will be integrated into the more practical building of circuits. And then you’ll see how using an active device like a transistor or op-amp, the RLC elements contribute to resonance, or bypass, or DC stability, or AC stability, or drift, or bandpass.
