A 10 ohm fixed value resistor is connected to both ends of the 6V power supply and discharged within 10s A 10 ohm constant value resistor is connected to both ends of a 6V power supply. How much heat is released in 10s? How much electric energy is consumed?
P=UI=U^2/R=6*6/10=3.6W
Heat released in 10s q = electric energy consumed in 10s e
Q=E=Pt=3.6*10=36J
A 10 ohm constant value resistor is connected to both ends of a 6V power supply. How much heat is released in 10s? How much electric energy is consumed?
Is electric energy the same as electric work
Power P = u ^ 2 / r = 6 ^ 2 / 10 = 3.6 (W)
A resistor is a device that converts electrical energy into heat energy. The heat released in 10 seconds is:
Q＝Pt＝3.6*10＝36（J）
According to the principle of conservation of energy, the energy consumed is equal to the heat released, which is also 36j
When a resistance wire is connected to a 36 V power supply and the heat generated in 10 s is 216j, the electric power of the resistance wire is? Resistance is? Detail
P＝Q/t=216/10= 21.6W
U^2/R=21.6
36*36/R=21.6
R = 60 Ω
How much heat does a 60 ohm resistance wire connect to a 36V power supply generate in 5 minutes!
According to Joule's law, q = (u ^ 2 / R) * t = (36 ^ 2 / 60) * 300 = 6480j
