Series And Parallel Circuits

Explanation
This is an example of a parallel circuit because in a parallel circuit, the components are connected in such a way that there are multiple pathways for the current to flow. In this case, the components are connected in parallel, allowing the current to divide and flow through each component separately.

Explanation
The total resistance in a circuit is calculated by adding up the resistances in parallel. 
1/R = 1/10 + 1/2 + 1/1 = 16/10
R = 10/16 = 0.625 kilo ohms = 625 ohms

Explanation
The given answer is "Series" because in a series circuit, the components are connected one after another, creating a single path for the current to flow. In this type of circuit, the current remains the same throughout, while the voltage is divided among the components.

Explanation
The total resistance in a series circuit is equal to the sum of the individual resistances. In this circuit, there are three resistors connected in series: R1 (100 Ohms), R2 (300 Ohms), and R3 (400 Ohms). Therefore, the total resistance is 100 Ohms + 300 Ohms + 400 Ohms = 800 Ohms. However, there is an additional 1 Ohm resistor connected in parallel with R3. When resistors are connected in parallel, the total resistance is given by the formula 1/RTotal = 1/R1 + 1/R2 + 1/R3. Plugging in the values, we get 1/RTotal = 1/800 + 1/1, which simplifies to 1/RTotal = 1/800 + 1. Solving for RTotal, we get RTotal = 1/(1/800 + 1) = 199 Ohms.
