📌 Understanding Ohm’s Law
Ohm’s Law states the relationship between voltage, current, and resistance in an electrical circuit. It is expressed as:
Voltage (V) = Current (I) × Resistance (R)
The unit of voltage is **Volts (V)**, current is **Amperes (A)**, and resistance is **Ohms (Ω)**.
📌 Examples of Ohm’s Law Calculation
| Current (A) | Resistance (Ω) | Voltage (V) |
|---|---|---|
| 2 | 10 | 20 |
| 5 | 4 | 20 |
| 3 | 8 | 24 |
❓ FAQs
Q1: How do I calculate voltage using Ohm’s Law?
✅ Voltage is calculated using the formula **V = I × R**, where I is current and R is resistance.
Q2: What is the unit of resistance?
✅ The unit of resistance is **Ohms (Ω)**.
Q3: Can resistance be zero?
✅ In an ideal conductor, resistance is zero, but real-world materials always have some resistance.
Q4: What happens to voltage if resistance increases?
✅ If resistance increases while current remains constant, voltage increases proportionally.
Q5: How does current affect voltage?
✅ Voltage increases with increasing current when resistance remains constant.
