Q2. For the RL circuit, shown in figure (1), the switch has been in position “a” for a long time, before switching to position “b”, at t = 0. Find a) a time-expression for the current through the inductor, i(t), for t > 0, b) the values of v(0- ), v(0+ ), and v(∞), and c) the powers dissipated in the 3-Ω resistor, at t = 3 ms
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).
