Powering Up Your Math: Five Calculations that Electrical Engineers Should Know How to Do Electrical engineers are a unique breed. Their work is mathematically demanding, and they constantly face challenging technical problems. An electrical engineer might derive circuit equations or a semiconductor model...
After you've determined the load limit of your joists, you can use that figure to determine the total acceptable load for the room or building in question. In the example, the floor area of the room is approximately 112 square feet. With an evenly distributed live load of 30 psf, which...
When bipolar transistors are connected in parallel, always make sure to add a calculated emitter resistor for each transistor. This resistor enables the BJTs to share the load current and thermal dissipation uniformly, which solves the thermal runaway problem in BJTs ...
Common Pitfalls to Avoid:Learning from previous mistakes and avoiding repeating them is always helpful. It would help if you understood the arguments. Check your answers and finalize your calculations while dividing complex numbers. Common Challenges of Complex Numbers in IBDP Math: ...
Consider a 5Ω load connected to a 10V DC source; here, the voltage remains constant, simplifying power calculation to 20W. But instead of a DC source, say we use an AC source. In this condition, the value of voltage is varying with respect to time, as shown in the figure below. ...
Off-grid solar is a great way to be energy efficient, but it needs proper planning. Learn how to size your solar array with our expert tips.
The above calculations should provide a helpful example of how to calculate your EV solar charging requirements. Just plug your specific numbers into the above formulas. However, there are numerous additional factors you need to consider before making a purchase decision, some of which were mentioned...
