A circuit contains two resistors connected in parallel. The value of R1 is 2,000 and the value of R2 is

4,200. What is the total resistance in this circuit?

A. 2,709

B. 6,200

C. 1,355

D. 987

For any two resistors in Parallel you can use the formula for total resistance as;

R total = Product / Sum

Rt = (R₁R₂) / (R₁ + R₂) R₁ = 2000, R₂ = 4200

Rt = (2000*4200) / (2000 + 4200) Use calculator.

= 1354.8

Total resistance = 1355 C.
