$Two resistors of R_{1} = 2 Ω and R_{2} = 4 Ω are connected in series. What is the equivalent resistance R_{e q} ?$

A. $1.33 Ω$
B. $2 Ω$
C. $4 Ω$
D. $6 Ω$

Show correct answer & step-by-step solution

Correct answer: D — $6 Ω$

Solution

For series connection, R_{e q} = R_{1} + R_{2} = 2 Ω + 4 Ω = 6 Ω .
