*Question T5A01:
Electrical current is measured in which of the following units?*  

*Correct Answer is  D: Amperes*  

### AI Response: (may contain errors)  

Electrical current is measured in which of the following units? The correct answer is:

**D: Amperes**

### Explanation:

1. **Why the correct answer is correct:**
   - Current is defined as the flow of electric charge. The unit of measurement for electric current is the ampere (A). One ampere is equivalent to one coulomb of charge passing through a point in a circuit per second.

2. **Why the other choices are incorrect:**
   - **A: Volts**: Volts measure electric potential or voltage, not current. Voltage is the force that pushes electric charges through a circuit.
   - **B: Watts**: Watts measure electrical power, which is the rate at which electrical energy is consumed or produced. Power can be calculated using the formula:
     $$
     P = V \times I
     $$
     where $P$ is power in watts, $V$ is voltage in volts, and $I$ is current in amperes.
   - **C: Ohms**: Ohms measure electrical resistance, which is the opposition to the flow of current in a circuit. The relationship between voltage, current, and resistance is described by Ohm's Law:
     $$
     V = I \times R
     $$
     where $R$ is resistance in ohms.

### Summary:
- Current is measured in **amperes** (A).
- Voltage is measured in **volts** (V).
- Power is measured in **watts** (W).
- Resistance is measured in **ohms** (Ω). 

Understanding these units and their relationships is crucial for grasping the fundamentals of electrical circuits.
