Question

Observe the above diagram and answer the following. 

a) Are all the resistors connected in parallel or series? 

b) What is the equivalent resistance of the combination of three resistors? 

c) In this system, which physical quantity is constant? 

d) If R₁ = 2Ω, R₂ = 3Ω, R₃ = 4Ω. find equivalent resistance.

Answer 1

a) Connected in series. 

b) R_eq = R₁ + R₂ + R₃

c) Current (I) 

d) R_eq = R₁ + R₂ + R₃ 

=2 + 3 + 4 = 9Ω
