கருத்து:

மின்தடையத்தால் சிதறடிக்கப்பட்ட திறன் பின்வருமாறு வழங்கப்படுகிறது:

\(P=I^2R=\frac{V^2}{R}\)

I = மின்தடையின் குறுக்கே பாயும் மின்னோட்டம்
 
V = மின்தடையின் குறுக்கே மின்னழுத்தம்
 
கணக்கீடு:
 
கொடுக்கப்பட்டவை P = 100 வாட்ஸ் மற்றும் R = 50 Ω

\(I=\sqrt {\frac{P}{R}}=\sqrt{\frac{100}{50}}\)

I = 1.414 A
