Why does pressing one switch or the other affect the direction the motor spins? Select the best answer below. O Either switch will create a path to ground when closed, completing the circuit and allowing current to flow. O Both sides of the motor are connected to high potential through equal amounts of resistance. There is no potential difference across the motor until one side or the other is pulled low by closing a switch, causing a difference in potential across the motor. The direction of current flow through the motor will be determined by which side is pulled low. O With no available connection to ground, current is stuck in an endless loop. Since that loop is connected to high potential by two paths with equal resistance, the current is divided equally in both directions. Closing either switch creates a path to ground, allowing current to "exit" the loop like leaving a freeway. Current from the opposite side must travel further, weakening the potential on that side. This creates a potential difference across the motor in that direction, causing the motor to spin. O Only the side where the switch is closed forms a complete circuit, so the motor must spin in that direction.

### Step-by-Step Analysis of the Circuit

#### Circuit Description:
Below is a detailed transcription and description of the given circuit diagram. The circuit comprises the following components:

1. **PSB (Power Supply Battery)**: A 5V power source supplies the circuit.
2. **R1 and R2**: Two resistors, each with a resistance of 50 ohms, are connected in the circuit.
3. **SW1 and SW2**: Two switches that control the flow of current through different parts of the circuit.
4. **M1**: A motor, denoted as M1 with a rating of 3V, indicating it operates optimally at 3 volts.

#### Diagram Analysis:
- **Power Supply (PSB)**: Located on the left side of the circuit, it provides a 5V potential difference.
- **R1 (50 Ω Resistor)**: Connected in series with the power supply and the motor M1. It limits the current flowing through this part of the circuit.
- **SW1 (Switch 1)**: Connected in series between the power supply and the motor M1. When closed, it allows current to flow through the motor.
- **Motor (M1)**: Positioned in parallel with SW1. It operates with the voltage provided and rotates when the circuit is complete.
- **R2 (50 Ω Resistor)**: Connected in parallel with M1 and SW1, further limiting the current within the loop it forms.
- **SW2 (Switch 2)**: Connected in series with R2. When SW2 is closed, current flows through R2.
  
#### Operation of the Circuit:
1. When **SW1** is closed, the circuit completes through the top path (which includes R1 and M1). 
2. The motor M1 will receive a voltage drop across it and operate.
3. **SW2** does not affect the operation of M1 directly but offers another path for current when closed. 
4. If **both SW1 and SW2** are closed, current will have multiple paths to flow through, affecting the overall current distribution based on the resistance provided by R1, R2, and the motor.

Use this configuration to answer specific questions about current, voltage drops, and the operation of the circuit depending on the states (open or closed) of SW1 and SW2. This knowledge relates to fundamental concepts in DC circuits, such as Oh
