What objects can be used as resistors?

Resistor Materials

• Wirewound (WW)
• Carbon Composition (CCR)
• Carbon Film.
• Metal Film.
• Metal Oxide Film.
• Foil.

What are three everyday objects that act as resistors?

Examples of Resistors

• Street Lighting. The street lights get automatically switched on in the evening and switched off in the sunlight.
• Laptop and Mobile Chargers.
• Temperature Control.
• Fan Speed Controller.
• Measuring Electrical Current.
• Temperature Sensor.
• In-Circuit Functioning.
• Dividing Voltage.

What could be used as a resistor in a circuit?

Ohm’s Law explains that the voltage difference in an electrical circuit is the product of the electrical current value (in Amperes) multiplied by the circuit resistance value (in Ohms). Because of this, even a good electrical conductor, such as metal wire, can be used as a resistor.

What household items use resistors?

Appliances such as electric heaters, electric ovens, and toasters all use resistors to turn current into heat, then using the heat lost from this resistor to warm the surrounding area.

How is a pencil a resistor?

As compared to other types of resistors this resistor also offers resistance to the flow of electricity through it. In fact the lead inside the pencil consists of properties of an electrical resistor and thus it acts as a resistor.

Is a light bulb a resistor?

The reason a light bulb glows is that electricity is forced through tungsten, which is a resistor. The energy is released as light and heat. A conductor is the opposite of a resistor.

What are some items you use daily that add resistance to an electrical circuit?

For any specific value of the input, we can calculate the resistance, current and thus power flowing through Ohm’s Law.

• Electric Heaters. The electric heaters are the common appliances used in winters throughout the world.
• Electric Kettles and Irons.
• Design of Electric Devices.
• Fuse Design.
• Mobile or Laptop Charger.

Can a pencil be used as a resistor in a circuit?

Yes, the pencil that we use in our day-to-day activities can be used as a resistor in electrical networks. As compared to other types of resistors this resistor also offers resistance to the flow of electricity through it.

Is a battery a resistor?

A battery can be thought of as a perfect voltage source with a small resistor (called internal resistance) in series. The electric energy density produced by the chemistry of the battery is called emf, but the amount of voltage available from the battery is called terminal voltage.

How many resistors can be combined in a circuit?

Resistors can be combined in two ways; series and parallel. Combination of more than one resistor is called equivalent resistor. We first look at the resistors in series; a. In this types of circuit, amount of currents passing through the resistors are equal and this current comes from the battery.

What is the object that completed the circuit?

Objects that completed the circuit made the light bulb light up. Those objects are conductors. They conduct electricity. Most other materials, like plastic, wood, and glass are insulators. An insulator in an open circuit does not complete the circuit, because electrons cannot flow through it!

What happens to the equivalent resistance when two resistors are connected parallel?

Sum of the currents in each branch is equal to the current coming from battery. b. Since the two ends of each resistor are connected to the same points, potential differences of each resistor are equal. When you add new resistors to the circuit in parallel, equivalent resistance of the circuit decreases.

What is the function of a resistor in an electronic circuit?

In an electronic circuit, the basic function of a resistor is to limit the current to a safe value so that the associated sophisticated parts can function properly. it may be virtually impossible to build an electronic circuit without involving resistors.
