Electronics: Resistors in parallel

From relation for calculating the resistance of parallel combination of resistors:


Calculate the R, if R1 = 2Ω a R2 = 15Ω

Correct result:

R =  1.76 Ω


R = \dfrac{1}{ \dfrac{1}{ 2}+\dfrac{1}{ 15}} = 1.76 \ &\text{Omega};

We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
