Electric Lamp: A Comprehensive Overview

An electric lamp of 100 ohm

An electric lamp, a ubiquitous illumination device, comprises several essential components. It consists of a filament, typically made of tungsten, housed within a glass bulb. The bulb is filled with an inert gas, such as argon or nitrogen, to prevent the filament from oxidizing.

The filament, when energized by an electric current, glows incandescently, emitting light.

Electrical Properties

Electrical resistance, a fundamental property of materials, measures the opposition to the flow of electric current. It is directly proportional to the length of the conductor and inversely proportional to its cross-sectional area. The resistance of the filament in a 100-ohm electric lamp is 100 ohms.

Resistance plays a crucial role in determining the current flow through the lamp. According to Ohm’s Law, the current (I) flowing through a conductor is directly proportional to the voltage (V) applied across it and inversely proportional to its resistance (R).

In this case, with a voltage of 120 volts applied across the lamp, the current flowing through it can be calculated as:

I = V/R = 120 V / 100 ohms = 1.2 A

Power Consumption, An electric lamp of 100 ohm

Electrical power, measured in watts, represents the rate at which electrical energy is transferred. It is calculated by multiplying the voltage across a component by the current flowing through it. In the case of the 100-ohm lamp, with a voltage of 120 volts and a current of 1.2 amps, the power consumption can be determined as:

P = V x I = 120 V x 1.2 A = 144 watts

Factors such as the resistance of the filament, the voltage applied, and the efficiency of the lamp influence its power consumption.

Circuit Analysis

A simple circuit involving the 100-ohm lamp can be constructed by connecting it in series with a voltage source and a switch. Using Ohm’s Law and Kirchhoff’s Laws, the circuit can be analyzed to determine the voltage across the lamp.

Ohm’s Law states that the voltage (V) across a component is equal to the current (I) flowing through it multiplied by its resistance (R). Applying this law to the lamp, we get:

V = I x R = 1.2 A x 100 ohms = 120 volts

Therefore, the voltage across the lamp is 120 volts.


Electric lamps have a wide range of applications in various settings. They are commonly used for general illumination in homes, offices, and public spaces. Specialized lamps, such as halogen lamps and fluorescent lamps, are employed in applications requiring specific lighting characteristics.

Different types of lamps cater to specific needs. Incandescent lamps, with their warm, yellowish glow, create a cozy atmosphere. LED lamps, known for their energy efficiency and long lifespan, are gaining popularity in both residential and commercial settings. Compact fluorescent lamps (CFLs) offer a balance between energy efficiency and affordability.

Safety Considerations

Electric lamps, while providing illumination, pose potential hazards that must be addressed. High temperatures generated by incandescent lamps can cause burns if touched. Broken glass from a shattered bulb can also be hazardous.

Precautions should be taken when handling and using lamps. Never touch a hot lamp, and allow it to cool down before handling. Replace damaged or broken lamps promptly to avoid electrical hazards. Follow safety regulations and standards related to lamp usage to ensure safe operation.

FAQ Summary: An Electric Lamp Of 100 Ohm

What is the significance of resistance in an electric lamp?

Resistance, measured in ohms, determines the flow of current through the lamp. A higher resistance value, like 100 ohms, limits the current flow, resulting in reduced power consumption and a longer lifespan for the lamp.

How can I calculate the power consumed by an electric lamp?

To calculate the power consumption, multiply the voltage applied across the lamp by the current flowing through it. For instance, a 100-ohm lamp connected to a 12-volt power source would consume 1.44 watts of power (P = V x I = 12V x 0.12A).

What safety precautions should I take when handling electric lamps?

Always ensure the lamp is securely installed and the wiring is in good condition. Avoid touching the lamp while it’s turned on, as the high temperatures can cause burns. Keep flammable materials away from the lamp to prevent fire hazards.
