If you're trying to figure out **amps** and **fuse ratings**, you're likely referring to charts that specify the **current-carrying capacity** (ampacity) of wires and the appropriate fuse or circuit breaker sizes. These charts help ensure that the wire and fuse can safely handle the electrical load without overheating or causing a fire.

### Common places to find these charts:
1. **Wire Ampacity Charts**: These show the maximum current that a wire of a certain gauge (AWG) can carry without overheating. For example:
   - **14 AWG** wire is rated for **15 amps**.
   - **12 AWG** wire is rated for **20 amps**.

2. **Fuse Rating Charts**: These list the appropriate fuse size based on the current expected in the circuit. For example:
   - If you have a circuit with 20 amps of current, you would typically choose a fuse rated for **25 amps** to allow a small buffer.

### Here’s a basic guide:

| **Wire Gauge (AWG)** | **Maximum Ampacity (Amps)** | **Common Fuse Size**   |
|----------------------|----------------------------|------------------------|
| 14 AWG               | 15 Amps                    | 15 or 20 Amp Fuse      |
| 12 AWG               | 20 Amps                    | 20 or 25 Amp Fuse      |
| 10 AWG               | 30 Amps                    | 30 or 35 Amp Fuse      |
| 8 AWG                | 40-55 Amps                 | 50 Amp Fuse            |
| 6 AWG                | 55-75 Amps                 | 60 Amp Fuse            |

You can find these charts in:
- **Electrical code books** (like the **Canadian Electrical Code**)
- Manufacturer datasheets for wiring or fuses
- Online references for electrical standards

### Added Key Concepts:
1. **Diode Forward Voltage Drop**: Silicon diodes typically have a 0.7V drop when forward biased.
2. **Load Line Analysis**: Helps determine the operating point of a diode by plotting voltage and current on a graph.
3. **Energy in a Capacitor**: Energy stored in a capacitor depends on capacitance and voltage squared.
4. **Metric Unit Conversions**: Remember to use common prefixes like milli, micro, kilo, and mega when working with smaller or larger units.                 Without compromising for any of the data and information because it is also crucial, I need you to summarize these information altogether as minimalistic and as neat as possible so I could use it as my study/cheat sheet/formula sheet for my test tomorrow
