What is the type of relationship between current and potential difference?
What is the type of relationship between current and potential difference? The current in a circuit is directly proportional to the electric potential difference impressed across the circuit and inversely proportional to the resistance of the circuit. What is potential difference unit? The potential difference between points A and B, VB – VA, is defined […]
Are AC and DC capacitors interchangeable?
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 […]

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 […]
Does altitude affect cooking time?
Does altitude affect cooking time? At high altitudes: Air pressure is lower, so foods take longer to cook. Temperatures and/or cook times may need to be increased. Water boils at a lower temperature, so foods prepared with water (such as pastas and soups) may take longer to cook. How do you bake at elevation? High-Altitude […]
