The continuos flow of electrons from a negatively charged point to a positively charged point is called__________.

Options

A. electric charge
B. electric current
C. speed
D. velocity

Answer

**Step-by-Step Solution:**

1. **Understanding the Flow of Electrons**:
- In a circuit, electrons move from the negatively charged terminal (source) to the positively charged terminal (sink). This movement is essential for the functioning of electrical devices.

2. **Definition of Electric Current**:
- The continuous flow of electrons from a negatively charged point to a positively charged point is defined as electric current.

3. **Notation of Current**:
- Electric current is denoted by the symbol "I".

4. **Mathematical Representation**:
- Electric current can also be mathematically expressed as the rate of flow of charge. The formula is given by:
\[ I = \frac{Q}{t} \]
where \( I \) is the current, \( Q \) is the charge, and \( t \) is the time taken for that charge to flow.

5. **Conclusion**:
- Therefore, the answer to the question is: The continuous flow of electrons from a negatively charged point to a positively charged point is called **electric current**.
