Interpretation Introduction

**(a)**

**Interpretation:**

The voltage V_{2} should be calculated.

**Concept introduction:**

When resistors are in series, a voltage divider. V = V_{1} + V_{2} + V_{3}

The current in a series circuit is everywhere the same. In other words, I = I_{1} = I_{2} = I_{3}

The total resistance Rs of a series circuit is equal to the sum of the resistances of the individual components. R_{s} = R_{1} + R_{2} + R_{3}

Ohm’s law;

Ohm’s law describes the relationship among voltage, resistance, and current in a resistive series circuit.

V = IR

Interpretation Introduction

**(b)**

**Interpretation:**

The power loss in resistor R_{2} should be determined.

**Concept introduction:**

When resistors are in series, a voltage divider. V = V_{1} + V_{2} + V_{3}

The current in a series circuit is everywhere the same. In other words, I = I_{1} = I_{2} = I_{3}

The total resistance Rs of a series circuit is equal to the sum of the resistances of the individual components. R_{s} = R_{1} + R_{2} + R_{3}

Ohm’s law;

Ohm’s law describes the relationship among voltage, resistance, and current in a resistive series circuit.

V = IR

V = Voltage I = Current R = resistant

Power rule;

P = V I

P = Power V = voltage I = Current

Interpretation Introduction

**(c)**

**Interpretation:**

The fraction of total power lost by the circuit would be dissipated in in resistor R_{2} should be calculated.
