What is relation between half life and mean life?
What is relation between half life and mean life? It turns out that the mean life equals the half life divided by the natural logarithm of 2 (about 0.693). The mean life also turns out to exactly equal the number τ that appears in the exponential term e−t/τ involved with describing decay or growth, called […]

Why does the voltage increase when the current decreases?
Why does the voltage increase when the current decreases? Since the ohmic losses in a transmission line are proportional the square of the current, reducing the current by 50% cuts the power loss by 75%. The current required to carry a given power decrease when you increase the voltage because the power is the product […]
