If two identical resistors are connected in s3ls x/hves8(a,qsvt( k1fx1 ze+fmlq3uqqs7c4 ft4t qc:9m v -ries to a battery, does the battery have to supply more pomt qsmu7q 4f f3tv4lcq:c+9 -qwer or less power than when only one of the resistors is connected? Explain.
参考答案: The power supplied by the battery
is the product of the battery voltage times the total current flowing from the
battery. With the two resistors in
series, the current is half that with a single resistor. Thus the battery has to supply half the power
for the two series resistors than for the single resistor.
