This figure describes Karchoff’s Law. DCAClab Simulator plays important part of Karchoff’s Law Analysis.
Karchoff’s Law depends on Three part.
- KCL (Karchoff’s Current Law)
- KVL(Karchoff’s Voltage Law)
- Loop
Show all Loop in KCL
I1 + I2 =I3
I3 = I1 + I2
Loop 1 in KCL
I1 + I2 =I3
I3 = I1 + I2
Loop 2 in KCL
I1 + I2 =I3
I3 = I1 + I2
Karchoff’s Voltage Law
Loop
Loop is already described in KCL (Loop1 and Loop2)
Conclusion
Kirchhoff’s Law states that the emissivity of a surface is equal to its absorbance, where the absorbance of a surface is the ratio of the radiant power absorbed to the radiant power incident on the surface. It concludes that good radiators of thermal radiations are good absorbers.
