In a parallel circuit, the current is divided among the electrical gadgets connected. This is in contrast to a series circuit where the current remains constant throughout the circuit.

One major disadvantage of a series circuit is that if one component fails, the entire circuit is broken, and none of the components works. This can lead to a complete failure of the electrical system.

In a series circuit, the current is constant throughout. However, electric bulbs and heaters require currents of widely different values to operate properly, making it impractical to connect them in series.

It is possible to replace the three resistors joined in series by an equivalent single resistor (R) of resistance, such that the potential difference (V) across it and the current (I) through the circuit remain the same. This equivalent resistance ...

In a series circuit, the current (I) remains constant throughout. The current through each resistor in the series is also equal to the total current flowing through the circuit. This is a fundamental characteristic of series circuits.

The total potential difference (V) across a combination of resistors in series is equal to the sum of potential differences (V1, V2, V3) across the individual resistors. In series circuits, the potential differences add up, reflecting the additive nature of ...

The application of Ohm’s law to combinations of resistors aims to understand and analyze the behavior of complex electrical circuits. Ohm’s law provides a fundamental relationship between current, voltage, and resistance, and its application to resistor combinations allows for the ...

Resistors are frequently used in various combinations in electrical gadgets to control the flow of electric current. These combinations help regulate the current and adjust the potential difference across different parts of the circuit, allowing for the proper functioning of ...

The current through a conductor depends on its resistance and the potential difference across its ends. These factors were explored in the preceding sections when discussing simple electric circuits.

Tungsten is used almost exclusively for filaments in electric bulbs because it has a high melting point, allowing it to withstand the intense heat generated by the filament during illumination. On the other hand, copper and aluminium are chosen for ...
