When a capacitor holding an initial electrical charge of 60 microcoulombs (µC) is discharged through an electrical circuit, the remaining charge on the capacitor is q(t) = 60e-t/4 , where t is time elapsed in seconds. (a) Find q'(t), the electrical current in the circuit, as a function of t. (b) When is the magnitude of the electrical current in the circuit the greatest, and what is its value at this time?
Sinusoids And Phasors
Sinusoids are defined as the mathematical waveforms that are used to describe the nature of periodic oscillations.
Circuit Theory
Electric circuits are a network that comprises of a closed-loop, which helps in providing a return path for the current through a switch. When the switch is activated, the load operates, and the current accepts a path to finish the circuit at a low potential level from the opposing high potential level. Electric circuits theory is a linear analysis that helps in establishing a linear relation of voltage and current for R (resistance), L (inductance), and C (capacitance).
