If two identical resistwd6 wea x.:hw xg4rh/;ors are connected in se nzcyp -2s7cp5ries to a battery, does the battery have to supply more power or less power than when only one of the resistors is connected? Explain. c5pcpy7 zn-2s
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.
