Identify the expression for rectification efficiency from the following.(a) η=\(\frac {ac \, input \, power \, from \, transformer \, secondary}{dc \, power \, delivered \, to \, load}\)(b) η=dc power delivered to load × ac input power from transformer secondary(c) η=dc power delivered to load + ac input power from transformer secondary(d) η=\(\frac {dc \, power \, delivered \, to \, load}{ac \, input \, power \, from \, transformer \, secondary}\)This question was posed to me by my school teacher while I was bunking the class.My doubt stems from Semiconductor Electronics topic in portion Semiconductor Electronics : Materials, Devices and Simple Circuits of Physics – Class 12 |
