Are AC and DC capacitors interchangeable? AC capacitor does not have polarity, but the constructions are generally based on films without any kind of electrolyte. DC is just a special case where the polarity of the voltage does not change, so you can use AC capacitors – as is – in a DC application. Why […]
Does heat affect electricity?
Does heat affect electricity? Temperature affects how electricity flows through an electrical circuit by changing the speed at which the electrons travel. This is due to an increase in resistance of the circuit that results from an increase in temperature. Likewise, resistance is decreased with decreasing temperatures. How can you heat your home without electricity? […]
What are the types of radio stations?
What are the types of radio stations? Different types of radio Conventional FM: As previously mentioned, conventional FM is a popular technology in analog radio. MPT1327: Perhaps the most widely used analog trunking technology today is called MPT 1327. Tetra: As the world becomes more digital, a number of digital radio technologies have emerged. Who […]
Does an object with mass always have momentum?
Does an object with mass always have momentum? An object with mass will have momentum. An object which is moving at a constant speed has momentum. An object can be traveling eastward and slowing down; its momentum is westward. Momentum is a conserved quantity; the momentum of an object is never changed. Can any object […]
What happens when a capacitor is short circuited?
What happens when a capacitor is short circuited? A short circuit here means that there is no resistance (impedance) between the two terminals of the shorted capacitor. The vertical wire drawn next to the vertical capacitor shorts the two terminals of the capacitor. This means you can ignore the shorted capacitor — it has no […]
What is the z-score for a 95% confidence interval?
What is the z-score for a 95% confidence interval? 1.96 What is the relationship between sample size and margin of error? Answer: As sample size increases, the margin of error decreases. As the variability in the population increases, the margin of error increases. As the confidence level increases, the margin of error increases. What is […]
What is one effect of the uneven heating of Earth caused by the sun?
What is one effect of the uneven heating of Earth caused by the sun? Usually when we talk about uneven heating of the Earth’s surface we are discussing convection. The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and […]

Can one bacterium insert its DNA into another bacterium?
Can one bacterium insert its DNA into another bacterium? Conjugation is a process by which one bacterium transfers genetic material to another bacterium through direct contact. During conjugation, one of the bacterial cells serves as the donor of the genetic material, and the other serves as the recipient. What are F+ F and HFR strains? […]
What type circuit connection should a light bulb be connected to maintain maximum brightness?
What type circuit connection should a light bulb be connected to maintain maximum brightness? Answer. Placing cells in series increases the voltage in the circuit by 1.5 V for each cell. Increasing the voltage increases the brightness of the bulb. When a bulb in a series circuit is unscrewed all bulbs in the circuit go […]
