Can you test continuity on a live circuit? You can measure the voltage and the current of a live circuit and use those figures to calculate the resistance (Ohm’s Law), but you can’t actually measure the resistance of a live circuit. For a number of reasons, you need to turn the power off and measure […]

Who is credited with creating the first periodic table? British chemist John Newlands was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves. How did Moseley establish more accurate periodic table? by […]

What is the formula of center of mass? The center of mass can be calculated by taking the masses you are trying to find the center of mass between and multiplying them by their positions. Then, you add these together and divide that by the sum of all the individual masses. What is the Centre […]

How many electrons does a 60 watt light bulb pass per second? As Incandescent lamp is a resistive load , Current that will flow through bulb is 0.5 Amp. By definition 1 Amp is equal to one coulomb of charge per second. Charge of an individual electron 1.602 × 10^-19 coulombs. Hence 1 coulomb of […]

How do you measure moisture in the air? The amount of water vapor in the air can vary greatly on regional scales and must be measured at weather stations. There are several ways to measure and express this moisture content. One is using a psychrometer, which measures the dry bulb (actual air) temperature and what […]
