Question

in this schematic, the total resistance is a 50 ohms b 100 ohms c 1,000 ohms d 10,000 ohms

Explanation:

Step1: Identify resistor connection

The image shows two 100 - ohm resistors in series.

Step2: Apply series - resistance formula

For resistors in series, the total resistance $R_{total}=R_1 + R_2$. Here, $R_1 = 100\Omega$ and $R_2=100\Omega$. So $R_{total}=100 + 100=200\Omega$. But there is an error in the options provided. If we assume the resistors are in parallel, for two equal resistors $R$ in parallel, the formula is $R_{total}=\frac{R\times R}{R + R}$.

Step3: Calculate parallel resistance

If $R = 100\Omega$, then $R_{total}=\frac{100\times100}{100 + 100}=\frac{10000}{200}=50\Omega$.

Answer:

A. 50 ohms
