Calculation problems Question 5. You use a simple potentiometer circuit to transduce the displacement of a hand-grip to a voltage output that should be linearly related to displacement. If the total resistance of the potentiometer is R and the displacement 'x' is defined as a proportion of the total length of the potentiometer, show how connection of a load resistance RL in the output can cause an error in your measurement due to loading. Derive the relationship between output voltage and displacement and take two instructive examples to help in your demonstration: when RL is infinite, and when RL is equal to R (further simplify the output-displacement relation in each case). R O'Vout RL

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?
