The current through a 220 μF capacitor is given below. Use Ohm’s Law to find the voltage. Convert to polar form, find the impedance and complete the math, then convert back to the waveform at i1 = 1.5sin(2500t + 30°) mA and i2 = 4.7sin(200t – 40°) mA

A thin metallic foil is placed between the plates of a flat capacitor parallel to them. How does this affect capacity? What if you join a plate with a wire?

2. The capacitor in the following figure .......

An inductor is constructed by winding a coil of 100 turns around a magnetic core. The core is a cylinder with radius 0.5 cm and the core material has relative permeability of 1000. The coil covers a length of 10 cm. Determine the resulting inductance. Enter your answer in mH rounded to two decimal places.

Inductors are fundamental components in electronics and electrical circuits. They are passive devices that store energy in the form of a magnetic field when crossed by an electric current. Inductors consist of a wire wound around a core, often made of iron or another ferromagnetic material. The storage of magnetic energy in inductors is expressed in terms of inductance, measured in henries (H). What is the value of inductive reactance (XL​) in ΩΩ, exhibited by the inductor in the circuit below?
