What can I use in place of a resistor?

A good conductor, such as metal wire, can be used as a Resistor. Resistance can be adjusted by limiting the thickness of the wire or decreasing the path through it. Resistance can be controlled by wire.

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 are simple resistors?

A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. Resistors can also be used to provide a specific voltage for an active device such as a transistor. Another type of resistor is made from winding Nichrome or similar wire on an insulating form.

Can you make a homemade resistor?

To create a wirewound resistor, one piece of wire would have to serve as the path for the electrical current to flow from one end of the resistor to the other. To create a resistor with a small resistance (or Ohm) value, use a thicker, shorter wire as the path between the two electrical leads.

Can you replace a resistor with a wire?

Resistors are used to limit current for one reason or another by the designer of the circuit. Replacing them with a wire will increase current flow and risk some other part of the circuit overheating. A wire has much less resistance than a resistor.

Can a light bulb be used as a resistor?

A lightbulb is a resistor that gets hot enough to emitt light. So the answer to your question is – yes. Lightbulb is considered a load, sometimes your load is resistive so you can draw it as resistor, resistors also can be considered as load for example electric heater is just big resistor. A “load” is a circuit.

What material are resistors made of?

The resistive element is made from a mixture of fine carbon particles and a non-conductive ceramic material. The substance is pressed into a cylindrical shape and baked. The resistance value depends on the dimensions of the body and the ratio between carbon and ceramic material. More carbon means a lower resistance.

How are tiny resistors made?

These resistors are made from small rods of ceramic coated with metal such as a nickel alloy or a metal oxide such as tin oxide. The value of resistance is controlled firstly by the thickness of the coating layer; the thicker the layer, the lower the value of resistance.

How do you determine the resistance of a resistor?

The function of a resistor is to oppose the electric current through it. This is called electrical resistance, and is measured in the unit ohm. The resistance can be calculated with Ohms law, when the current is known and the voltage drop is measured: The resistance of a resistor is dependent on its material and shape.

Can you use a resistor to reduce voltage?

Reducing voltage in an electrical circuit with resistors is an efficient way for controlling electrical power. The most important aspect for the use of resistors is the correct sizing of that resistor so it will not burn out. By following a few basic procedures and the use of Ohms Law, you can reduce the voltage of most electrical circuits.

Is a resistor considered a voltage rise?

Other types of resistors A metal oxide varistor (MOV) is a special type of resistor that changes its resistance with rise in voltage: a very high resistance at low voltage (below the trigger voltage) and very low resistance at high voltage (above the trigger voltage). A thermistor is a temperature-dependent resistor.

What is the role of a resistor?

The main purpose of a resistor is to maintain specified values of voltage and current in an electronic circuit. A Resistor works on the principle of Ohm’s law and the law states that the voltage across the terminals of a resistor is directly proportional to the current flowing through it. The unit of resistance is Ohm.
