संकल्पना:
 
  • शक्ती: विद्युत प्रवाहाने केलेल्या कामाच्या दराला शक्ती म्हणतात. हे P द्वारे दर्शविले जाते. शक्तीचे SI एकक वॅट (W) आहे.
शक्तीचा अपव्ययद्वारे दिले जाते:
 
शक्ती (P) = V I = V2/R = I2 R
 
जेथे V हा रोधांतील संभाव्य फरक आहे, I विद्युत प्रवाह आहे आणि R हा रोध आहे.
 
गणना:
 
ते दिल्याप्रमाणे:
 
रोध (R) = 5 Ω
 
विद्युत प्रवाह (I) = 2 A
 
शक्ती (P) = I2 R = 22 x 5 = 20 W
