Question

What is the equivalent resistance of a circuit of two resistors R1 and R2 connected in series if R1 = 100 Ohms and R2 = 200 Ohms? A)400 Ohms B)500 Ohms C)800 Ohms D)150 Ohms E)300 Ohms

Answer 1

E) 300 Ohms

Explanation:

Given:

R1 = 100 Ω

R2 = 200 Ω

The equivalent resistance in a series circuit is the sum of each resistance, therefore:

`\begin{gathered} R_(eq)=R_1++R_2 \\ R_(eq)=100+200 \\ R_(eq)=300Ω \end{gathered}`

The equivalent resistance is equal to 300 ohms.
