- What does finite element analysis do?
- Finite element analysis (FEA) is a computer simulation technique used to solve complex engineering problems such as stress distribution, deformation, vibration, heat transfer and fluid dynamics. FEA decomposes a geometric structure into finite elements and uses mathematical equations to simulate the behavior of each element and approximate the entire structure. Its advantages include accuracy, efficiency, flexibility, visualization and predictability, and is widely used in industries such as automotive, aerospace, construction, medical and electronics.

- What are the factors that affect impedance?
- Impedance is the resistance to the flow of electrons in a circuit and is affected by: Resistance: The greater the resistance, the greater the impedance. Inductance: Inductance is proportional to frequency, increasing impedance. Capacitance: Capacitance is inversely proportional to frequency, increasing impedance. Frequency: In an AC circuit, impedance changes with frequency. Temperature: The resistance of some materials changes with temperature. Magnetic Fields: An external magnetic field changes the inductance of a conductor, thereby affecting the impedance. Geometry: Conductor shape affects resistance and inductance and thus impedance.

-
- The difference between impedance and resistance
- The difference between impedance and resistance is that impedance is a vector sum, including resistance, inductance and capacitance; resistance is pure resistance and is not affected by frequency. In applications, impedance is used for impedance matching, resonant circuits and sensing, while resistor is used for power calculations.

- What does pwm mean?
- Pulse width modulation (PWM) is a technique for controlling the power output of digital devices by varying the duty cycle of a signal. It works by sending a periodic sequence of pulses, where the high time (duty cycle) represents the percentage of high time in the entire cycle. PWM is widely used in areas such as motor speed control, LED dimming, audio amplification, and power management. PWM advantages include high power efficiency, wide control range, and ease of implementation. Limitations include harmonic distortion, noise generation, and sensitivity to interference and load changes.
