Series And Parallel Circuits

1. Is this a Series, Parallel or Combination circuit?

Series

Parallel

Combination

Cannot be Determined

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.

3. Is this an example of a Series or Parallel circuit?

Series Circuit

Parallel circuit

Combination circuit

Neither Parallel nor Series

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

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.

5. In the circuit shown the Total Resistance is calculated as:

0.016 Ohms

1300 Ohms

625 Ohms

100 Ohms

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 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

6. In the circuit shown the total resistance (to the nearest Ohm) is:

900 Ohms

186.72 Ohms

199 Ohms

194.55 Ohms

To find the total resistance, we need to analyze the series and parallel combinations of resistors in the circuit:

Identify Series Resistances:

R1 and R2 are in series: R1 + R2 = 100 Ω + 250 Ω = 350 Ω

R3 and R4 are in series: R3 + R4 = 350 Ω + 200 Ω = 550 Ω

Identify Parallel Resistances:

The combined resistance of (R1 and R2) is in parallel with the combined resistance of (R3 and R4).

Calculate Parallel Resistance:

Let Rp be the total resistance of the parallel combination.

1/Rp = 1/350 Ω + 1/550 Ω

1/Rp = 0.00514

Rp = 194.55 Ω
