A battery is comprised of 4 cells connected in parallel, each cell has an EMF with 1.2V and an internal resistance of 0.55 ohm. There is no load connected to the terminals. Solve for Vterm.

ighlight A 50-V independent voltage source supplies power to three resistors in the DC circuit shown in Figure P26. For each resistor, find the voltage drop and - current. Use Kirchhoff's Laws 50 V 75 1 333 N 22 N Ans: 601 mA

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?
