1. risingsunThe amount of current (I) flowing in a resistor is directly proportional to the voltage across it and inverly proportional to the resistance of the resistor. 2. A multimeter is a general-purpo meter capable of measuring DC and AC voltage, current, resistance, and in some cas, decibels. 3. The motherboard is the main circuit board inside the PC which holds the processor, memory and expansion slots and connects directly or indirectly to every part of the PC（Fig 9.1）. 4. Moore's law, which predicted that the number of devices integrated on a chip would be doubled every two years, was accurate for a number of years.
五、综合运用（每小题 20分，共 20 分）
C is commonly considered to be a structured language with some similarities to Pascal. In C, a block of code is a logically connected group of program statements that can be treated as a unit. You can create a block of code by placing lines of code between opening and closing curly braces. For example: if(x<10) { printf (“too low, try again”); ret_counter(-1); } The two statements after "if" that are between the curly braces are executed if x is less than 10. The two statements with the braces reprent a block of code. They are linked together: one of the statements cannot execute without the other also executing. (将上面的短文翻译成中文)
