What can be used as a resistor in a circuit?
All electrically conductive materials are somewhat resistive, too. Because of this, even a good electrical conductor, such as metal wire, can be used as a resistor. Resistance can be adjusted by limiting how thick the wire is, and by increasing or decreasing the conductive path through the wire.
Why would you connect a penny to a circuit?
Why did the person who made Circuit A probably connect the wires to a penny? a. They needed to use a penny to make the bulb light.
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 the application of resistor?
Resistor is used in power control circuit. It is used in DC power supplies. Resistors are used in filter circuit networks. It is used in amplifiers, oscillators, telecommunication and digital multimeter.
Can I use a fuse as a resistor?
A fuse limits overcurrent damage by opening the circuit above a certain current value. A fuse can be used as a resistor. There are even fusible resistors, which act as a resistor with a definite value but they also act like a fuse on overcurrent. 2.
What does a resistor look like on a diagram?
Resistors on a schematic are usually represented by a few zig-zag lines, with two terminals extending outward. Schematics using international symbols may instead use a featureless rectangle, instead of the squiggles.
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.
Why does the penny battery work?
When these electrodes are connected by a wire, electrons will move from one surface to the other, creating an electric current. In Volta’s battery and your penny battery, an oxidation reaction occurs at the zinc electrode that releases electrons and a reduction reaction occurs at the copper electrode that uses them.
What is the opposite of a resistor?
A conductor is the opposite of a Resistor.
What are the advantages of resistors?
Advantages of resistors Resistors are very cheap. Hence, it is easy to replace them. Resistors do not depend on the external source of voltage. Hence, external voltage or energy is not needed for operating the resistors.
How does it work and applications of resistor?
A conductor has low resistance, while an insulator has much higher resistance. Devices called resistors let us introduce precisely controlled amounts of resistance into electrical circuits. A resistor works by converting electrical energy into heat, which is dissipated into the air.
