*Question T5A05:
What is the electrical term for the force that causes electron flow?*  

*Correct Answer is  A: Voltage*  

### AI Response: (may contain errors)  

The correct answer to the question is **Voltage**.

1. **Why the correct answer is correct:**
   - Voltage, also known as electric potential difference, is the force that pushes electrons through a circuit. It is measured in volts (V) and represents the energy per unit charge available to move electrons. In simple terms, higher voltage means a stronger "push" on the electrons, leading to greater current flow.

2. **Why the other choices are incorrect:**
   - **Ampere-hours (B):** This is a unit of electric charge that represents the amount of current (in amperes) flowing over a period of time (in hours). It does not describe the force that causes electron flow.
   - **Capacitance (C):** This is the ability of a component (like a capacitor) to store electrical energy in an electric field. It is measured in farads (F) and does not relate to the force driving electron flow.
   - **Inductance (D):** This is the property of a conductor by which a change in current creates an electromotive force (EMF) in the same or nearby conductors. It is measured in henries (H) and is not the force that causes electron flow.

3. **Useful formulas or rules of thumb:**
   - The relationship between voltage (V), current (I), and resistance (R) in a circuit is described by Ohm's Law:
     $$
     V = I \times R
     $$
   - This formula shows that voltage is the product of current and resistance, reinforcing the idea that voltage is the driving force in an electrical circuit. 

Understanding these concepts will help you grasp the fundamental principles of electricity and prepare you for the Extra Class exam.
