1. The full-wave controlled bridge rectifier shown has an ac input of 120 Vrms at 60 Hz and a 52 load resistor. The delay angle is 30°. Determine the average current in the load, the power absorbed by the load and the source voltamperes. V₁ I sin cor H www + Vo

Trial example of how to use Kirchhoff analysis to determine the initial current in each section along with its direction and the potential difference across the load

You are an electrician working on an overhead crane. The crane uses a large electromagnet to pick up large metal pipes. The magnet must have a minimum of 200 VDC to operate properly. The crane has an AC source of 240 V. You are given four diodes that have a peak voltage rating of 400 V each. These diodes are to be used to form a bridge rectifier to convert the AC voltage into DC voltage. Is the voltage rating of the diodes sufficient? To the nearest volt, what will be the DC output voltage of the bridge rectifier?
