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
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
