In Simple Terms

Inductors oppose sudden changes in current.

Formula

The induced voltage (back EMF) is given by:

[
V = L \frac{di}{dt}
]

Where:

• V = induced voltage

• L = inductance

• di/dt = rate of change of current

---

Inductance: What Affects It?

The inductance value depends on:

1. Number of turns – More turns = higher inductance

2. Core material – Iron cores increase magnetic strength

3. Coil size – Larger coils store more magnetic energy

Once consumed, carbohydrates break down into glucose, which enters the bloodstream.
The hormone insulin helps cells absorb glucose to use it for energy.

If extra glucose isn’t needed immediately, it is stored as:

• Glycogen in the liver and muscles

• Fat if glycogen stores are full

Healthy vs. Unhealthy Carbohydrates

Healthy (Complex) Carbs

• Whole grains

• Fruits

• Vegetables

• Legumes

• Sweet potatoes

• Nuts & seeds

These foods contain fiber, vitamins, minerals, and antioxidants.

Unhealthy (Refined) Carbs

• White bread

• Cakes and pastries

• Sugary drinks

• White pasta

• Processed cereals

These raise blood sugar quickly and offer low nutritional value.

How Many Carbohydrates Do You Need?

The average adult’s diet should contain 45–65% of total calories from carbohydrates.

Daily Carbohydrate Calculation

If you consume 2,000 calories per day:

• 45% carbs: 900 calories → 225g

• 65% carbs: 1300 calories → 325g

1 gram of carbohydrate = 4 calories

Athletes and active individuals may need more carbohydrates, while low-activity individuals may require less.

Common Myths About Carbohydrates

Myth 1: “Carbs make you fat.”

Fat gain occurs when you consume more calories than you burn—not because of carbs alone.

Myth 2: “Low-carb diets are the healthiest.”

Low-carb works for some people, but long-term health relies on balanced eating.

Myth 3: “Sugar from fruit is bad.”

Fruit contains fiber, vitamins, and antioxidants—much healthier than refined sugar.

Carbohydrates are essential for a healthy body and active lifestyle. Choosing the right types—especially complex carbs and fiber-rich foods—provides long-lasting energy, supports brain function, and aids digestion. Instead of avoiding carbs, focus on balancing them wisely as part of a healthy diet.
