    Engineering Understanding First Order Circuits: DC vs. AC

    Hi, I'm confused with the solution given for this practice problem. All of these components are said to be in parallel, yet the current is worked out only across the resistors. I thought the inductor would be a short circuit to DC. Am I looking at this backwards, is it modelling the inductor...

    Resolving Forces in a Hanging Bag of Sand

    Homework Statement A bag of sand weighing 100 N is hanging on the end of a long, light rope. The bag is pulled to one side by a horizontal force so that the rope makes an angle of 250 with the vertical. Find the magnitudes of the horizontal force and the tension in the rope.The Attempt at a...

    Synthesised Sine wave VS Modified Square Wave inverters

    I am to contrast the difference between modified square wave, and synthesized sine wave inverter outputs. Am I to understand, that a modified square wave output is like a square wave, but the transtion to current flow in the other direction is delayed some at the zero point. This is to give...

    What Are the Major Ratings and Acronyms for MOSFETs?

    I'm doing a diploma in renewable energy from a technical college. I'm learning how the magic boxes with terminal screws on them regulate battery charging, convert 12/24V DC to 240 AC, convert 3 phase from a wind turbine to DC etc. I'm to learn briefly how the circuits work but not to the point...

    What Are the Major Ratings and Acronyms for MOSFETs?

    Homework Statement List the major device ratings for a MOSFET. The Attempt at a Solution Simple question yeah? Data sheets list about 20 ratings for each device, and they don't explain the acronyms. VBRDSS = Vegemite BReaD Salad Sandwich? Can someone help me trim them...

    Can Zener Diodes Maintain a Constant Voltage Regardless of Applied Voltage?

    I have trouble getting my head around Zener Diodes. If you reverse bias them, and apply a current, it will not conduct until the applied voltage reaches the Zener Voltage. Am I to understand that no matter how much voltage (within reason) you apply to the diode, its output voltage will always...
