Advantages of Parallel Connection over Series Connection
- Individual Control: Each device can be operated independently; if one device fails, others remain functional.
- Consistent Voltage: Each component receives the same voltage, ensuring uniform operation.
- Easier Fault Isolation: Faulty components can be easily identified and replaced without affecting the whole circuit.
- Flexible Design: More devices can be added without altering the existing setup.
V-I Graph Representing Ohm's Law
The V-I graph depicts the relationship between voltage (V) and current (I) for a resistor, demonstrating Ohm's Law (V = IR).
- Linear Relationship: The graph is a straight line through the origin, indicating that current increases linearly with voltage.
- Slope Significance: The slope of the line represents the resistance (R) of the component.
Heating Effect of Electric Current
The heating effect of electric current refers to the phenomenon where electric energy is converted into heat energy when current flows through a conductor due to its resistance. This effect is utilized in various applications, such as electric heaters and toasters.
Joule's Law
Joule's Law states that the heat produced (H) in a conductor is directly proportional to the square of the current (I) flowing through it, the resistance (R) of the conductor, and the time (t) for which the current flows.
Derivation of Joule's Law
- Formula: H = I²Rt
- I: Current (in amperes)
- R: Resistance (in ohms)
- t: Time (in seconds)
- Explanation: As current passes through a conductor, collisions between electrons and atoms generate heat. The amount of heat generated increases with higher current, longer time, and greater resistance, confirming that energy is dissipated as heat in electrical circuits. This principle is crucial in determining the safety and efficiency of electrical devices.
