What is a square root? The square root of a number answers the question "what number can I multiply by itself to get this number?". It is the reverse of the exponentiation operation with an exponent of 2, so if r 2 = x, then we say that "r is the root of x". Finding the root of a number has a special notation called the radical symbol: √. Usually the radical spans over the enti...


As a square root example if I know the 10,000 ohm resistor has a rating of 0.25 watts I can calculate the maximum worst case voltage that could appear across it, before damage could occur. This is found by taking the resistance value - multiplying the wattage rating - and finding the square root. Square root of 2500 is 50.
