What is the formula for electric power? A. P = IV B. P = VI C. P = VR D. P = IR 相关知识点: 试题来源: 解析 B。解析:文章中明确提到“The formula for electric power is P = VI, where P is power, V is voltage, and I is current.”。
The power of a power rule is an important exponent rule (law of exponent) used to simplify an expression of the form (xm)n, where the base x is raised to a power m and the entire expression xm is raised to the power n again. ...
You can refer to a cell, a set of cells, or a range of cells by using the A1 reference convention. In this convention, the letter refers to the cell's column and the number refers to the cell's row. The first column in a table is column A; the first row is row 1. The ...
Electric power is measured watts (W) in honor of the famous scientist, James Watt. Sometimes people refer to electric power by one word electricity, and though it is not completely accurate, electricity as power is measured in watts. In an electric circuit, electric power can also be calculat...
References: refer to individual cells or ranges of cells. A2 returns the value in cell A2. Constants: numbers or text values entered directly into a formula, such as 2. Operators: The ^ (caret) operator raises a number to a power, and the * (asterisk) operator multiplies. Use + and ...
If a formula refers back to one of its own cells, you must determine how many times the formula should recalculate. Circular references can iterate indefinitely. However, you can control the maximum number of iterations and the amount of acceptable change. Precision is a...
As this diagram demonstrates, power factor compares the real power (or power available to perform work) being consumed to the apparent power, or demand of the load. You can avoid power factor penalties by improving power factor. Poor power factor means that you’re using power inefficiently. ...
Power– Returns a number raised to a power. You can also use the^operator. Print- Opens the current screen in the default browser print dialog. Proper– Converts the first letter of each word in a string to uppercase, and converts the rest to lowercase. ...
