: 第一題不我一直算出解答的答案 請大家提供自己的算法
: 1.A circuit has a variable load,R. Power measurements show that the power into R
: is maximum at 100W with R=6歐姆. What current would flow if R were replaced
: by a 3歐姆 resistor? 答案:I=5.44A
第一題是最大功率轉移
依照題目可知道 電路是一的電壓源串連一個電阻（戴維寧形式）在加上一個負載
他說了最大功率100w可以知道串連的電阻也是6歐姆
v^2/R=100 R=6歐姆
故v=10√6 電壓源＝2*v＝20√6
之後題目又把6歐姆換成3歐姆
所以答案是I＝2*V/（6+3）＝5.44A
: 2.A student is testing a circuit containing batteries and resistor. The output
: voltage is 6.26V when measured with a good (assume idea)voltmeter,but 6.05V
: when a 600歐姆 resistor is connected across the output terminals. What current
: would result if the output were shot-circuited?
: 答案:0.301A
: 請大家幫幫忙 謝謝
