Unformatted text preview: over time. Let = L/R . You dont need an integrating factor this time. If your current goes to inFnity, you may have made a sign error. d) What is the expression for the initial energy stored in the inductor? e) What is the expression for the power dissipated in the resistor at any time t in terms of variables including t explicitly? f) Integrate the expression for power dissipated in the resistor from time zero to inFnity. Has energy been conserved? 032 qfull 00610 2 3 0 mod math: transformer stepup stepdown Extra keywords: transformer, step up, step down 6. You want to step up an AC potential by a factor of 3. a) What turn ratio N secondary /N primary must you use? b) What would be the ratio of the secondary to the primary current?...
