A resistance marked "1K ohm, 10W", the maximum current allowed to pass is_____ The maximum voltage allowed to be applied to both ends of the resistor is. When the voltage at both ends of the resistor is 40V, the actual power consumed is. (it is assumed that the resistance does not change with temperature)
Maximum current I = √ (P / R) = 0.1A
(1)P=U^2/R
U=√P*R=√10000=100V
(2)I=U/R=40/1000=0.04A
P=UI=40*0.04=1.6W
