When you first get hired to a job, the employer quotes your gross salary or gross hourly pay. But your net salary will most likely matter to you more in your day-to-day life....
At higher than normal operating temperatures, for every additional 15Â°F (8Â°C) battery life is decreased by 50 percent. Therefore, continued operation at an average cell temperature of 92Â°F (33Â°C) will reduce battery life to 50 percent of that typical at 77Â°F (25Â°C).
Temperature Coefficient of Copper. The Temperature Coefficient of Copper (near room temperature) is +0.393 percent per degree C. This means if the temperature increases 1Â°C, the resistance will increase 0.393%. You have 100 feet of 20 gauge wire and its resistance is 1.015 ohms at 20Â° C (room temp).
