Electrical resonance occurs when circuit element impedances cancel at specific frequencies. Resonant circuits generate higher voltages/currents than input. Resonance is used in wireless transmission for both reception and transmission

LC circuit consists of inductor and capacitor, oscillating energy without consuming it. Circuit behaves like harmonic oscillator, hence called tuned or tank circuit. Energy oscillates between capacitor and inductor until internal resistance causes it to die out
Parallel RLC circuits have common voltage across all components. Current through each branch is different from supply current. Total current is vector sum of branch currents
AC electricity is ubiquitous in power supply and electronics. Voltage and current vary sinusoidally with time. Impedance is voltage divided by current, different from resistance
NO2 contains one nitrogen atom bonded to two oxygen atoms. Total 17 valence electrons with one unpaired electron. Nitrogen is central atom surrounded by oxygen atoms
