Here is a table representing the relationship between power, circuit current, and resistance:
| Power (P) | Circuit Current (I) | Resistance (R) |
| ---------| --------------------| ---------------|
| P = I^2R | I = P/R | R = P/I^2 |
As you can see, the power in a circuit is equal to the product of the current squared and the resistance. The current in the circuit is equal to the power divided by the resistance. The resistance in the circuit is equal to the power divided by the current squared. These equations are fundamental to understanding the behavior of electric circuits.

Show how the tree in Figure 4.62 is represented using child/sibling pointer representation.
The tree in Figure 4.62 can be represented using child/sibling pointer representation as follows:
The root node has a null pointer for both child and sibling. Node A is the first child of the root and has a pointer to its sibling B. Node B has a pointer to its child C and a pointer to its sibling D. Node C has a null pointer for both child and sibling, while node D has a pointer to its child E and a pointer to its sibling F. Node E has a null pointer for both child and sibling, while node F has a pointer to its child G and a null pointer for its sibling. Node G has a null pointer for both child and sibling.
the file contains a character that connot be represented in the current code page(936)
这通常是由于文件中包含了当前代码页不支持的字符而引起的。在Windows操作系统中,代码页936是简体中文编码的默认代码页。如果打开一个文件时出现此错误,可能是因为文件中包含了非简体中文编码的字符,或者文件编码格式不正确。
解决此问题的方法之一是将文件的编码格式转换为当前代码页支持的格式。可以使用文本编辑器(如Notepad++)打开文件,并将编码格式转换为UTF-8或GB2312等简体中文编码格式。如果文件中包含非简体中文编码的字符,则需要手动更正这些字符。
另外,如果文件中包含的字符是必需的,但当前代码页不支持该字符,则可以尝试更改当前代码页。在Windows操作系统中,可以通过控制面板中的“区域和语言”选项更改代码页。
