What is the total resistance, in units of Ohms, for the circuit shown in the diagram below when measured from the terminals on the left where R1 = 25 Ohms, R2 = 26 Ohms and R3 = 20 Ohms?

(Answer needs to be within one decimal place, in units of Ohms.)

What is the total resistance in units of Ohms for the circuit shown in the diagram below when measured from the terminals on the left where R1 25 Ohms R2 26 Ohm class=

Respuesta :

Answer;

≈ 16.2 Ohms

Explanation;

R₂ and R₃ are in series; therefore to get total Resistance, we will use;

= R₂ + R₃

= 26 +20

= 46 Ohms

Then the two resistors (R₂ and R₃) combined and R₁ are in parallel to each other;

Therefore, using the formula for parallel resistors; 1/R₁ + 1/R(₂,₃)

1/Rt =1/25 +1/46

 1/Rt   =(25+46)/(25 ×46)

Rt = (25 ×46)/(25+46

   = 16.197

   ≈ 16.2 Ohms
