WebA resistor is an electrical component that restricts the flow of electrical current in a circuit. The analogy often used to explain its operation is to consider current as water flowing in a hosepipe; a resistor can be considered as a constriction in the pipe that limits the flow of water. Most people will be familiar with Ohm’s law: V=IR. WebFigure 1 shows a set of three typical HRC fuses used for electric motor circuit protection. They have a plastic carrier and base and are designed to be used with enclosed fuse links. HRC fuses are extremely consistent …

WebA fuse will pass current until the current is increased to a level that will cause the fuse to “open” the circuit, that the fuse will then no longer pass any current. A resistor will … WebAlso this resistor can easily be changed for a different value where different versions of a circuit may be built, using the same PCB. The tolerance band on a resistor indicates the spread of possible values of any particular resistor, for example a resistor marked as 47K Ω +/- 10% will have an actual value somewhere between 42.3K Ω and 51.7K Ω.

WebOct 3, 2024 · The voltage rating on the fuse can be higher than the voltage present on the circuit, but not the other way around. If a 250 V AC fuse is used on a device that uses 120 V AC, there should be no problem. If a 125 V AC fuse is used on a 250 V AC supply, the fuse will be damaged and the likelihood of arching is great when the fuse blows. Another ... WebApr 12, 2024 · Power dissipated in a resistor can be calculated using the formulas P = I 2 R or P = V 2 / R. Consider you are driving a LED of 2.2v with 12v with a 330 ohm resistor in series. In this case the power dissipation in the resistor will be. V Res = 12 – 2.2 = 9.8v. P = 9.8 2 / 330 = 0.29 Watt.
