1W 100 Ohm Resistor: A Comprehensive Guide
Overview
A 1W 100 ohm resistor is a type of electrical component that plays a crucial role in various electronic circuits. In this article, we will delve into the details of this component, its characteristics, and its applications.
What is a 1W 100 Ohm Resistor?
A 1W 100 ohm resistor is a type of fixed resistor that has a power rating of 1 watt and a resistance value of 100 ohms. It is a passive component that opposes the flow of electric current and converts some of the energy into heat.
Characteristics
Here are some key characteristics of a 1W 100 ohm resistor:
Power Rating: 1 watt
The power rating of a resistor indicates the maximum amount of power it can handle without overheating. In this case, the 1W rating means that the resistor can handle up to 1 watt of power.
Resistance Value: 100 ohms
The resistance value of a resistor determines how much it opposes the flow of electric current. A 100 ohm resistor will allow 10 mA of current to flow when connected to a 1V power source.
Tolerance: ±5% or ±10%
The tolerance of a resistor indicates how much its actual resistance value may vary from its nominal value. A ±5% tolerance means that the actual resistance value may be between 95 ohms and 105 ohms.
Operating Temperature: -55°C to +155°C
The operating temperature range indicates the temperature range within which the resistor can operate safely. In this case, the resistor can operate within a temperature range of -55°C to +155°C.
Applications
1W 100 ohm resistors have a wide range of applications, including:
Voltage Dividers
1W 100 ohm resistors can be used as voltage dividers to reduce the voltage level in a circuit.
