The region around the electric charge in which the electric force act is called an electric field or electrostatic field.
If the magnitude of charge is large, then it may create a huge force around the region. The electric field is represented by the symbol E. The SI unit of the electric field is newton per coulomb which is equal to volts per meter.
Properties of an Electric Field:
Properties of an Electric Field:
- The electric field line starts from the positive charge and ends at negative charge
- The number of field lines is directly proportional to the magnitude of the charge
- Electric field lines never intersect each other
- They are perpendicular to the surface charge
- The field is strong when the lines are close together, and it is weak when the field lines move apart from each other
- If the charge is single, then they start or end at infinity
- The line curves are continuous in a charge-free region

Answer:
Explanation:
- **Direction of Electric Field**:
When a voltage is applied, the direction of the electric field is always from Positive to Negative. This means that the electric field lines originate at the positive terminal and terminate at the negative terminal.
- **Conventional Current Direction**:
In a circuit, conventional current flows from the positive terminal of the voltage source to the negative terminal. This flow of positive charges creates an electric field in the opposite direction, from positive to negative.
- **Voltage Polarity**:
The positive terminal of a voltage source is at a higher electric potential compared to the negative terminal. Therefore, the electric field lines point away from the positive terminal and towards the negative terminal.
- **Effect of Voltage**:
Applying a voltage across a circuit creates an electric field that exerts a force on charged particles within the circuit, causing them to move in a specific direction. This movement of charges is what constitutes an electric current.
- **Conclusion**:
In summary, when a voltage is applied, the direction of the electric field is always from Positive to Negative, reflecting the flow of conventional current and the polarity of the voltage source.
