Resistor is defined as an electrical component which is used for controlling temperature and voltage. There are two types of resistors: linear resistor and non-linear resistor. Resistors are identified with the help of color codes. Resistor finds applica
An electric vehicle (car) is equipped with a large, high-voltage lithium ion battery and with a low-voltage lead battery used in engine vehicles as well. Both batteries need to be charged. The lithium ion battery is charged at a charging station, and the
We talk about resistors in Ohms. A resistor might be a 220 Ohm resistor, or it might be 6.8K Ohm resistor. To give you a frame of reference, something with an Ohm value of 1 or less is considered to be a very low resistance. Most wire you use in your projects will fit in this ...
What is resistance? Measuring resistance Resistance is useless? How resistors work How does the size of a resistor affect its resistance? Resistance and temperature Resistor color codes Find out moreWhat is resistance?Electricity flows through a material carried by electrons, tiny charged particles insi...
Higher resistance is provided by longer wire, whereas a wider cross-sectional area of wire helps in decreasing the resistance. Certain materials such as metals are known to be good conductors of electricity and hence provide less resistance. Temperature influences the electron structure and with ...
The temperature coefficient of resistance is defined as the change in the increase in the resistance of 1Ωresistorof a material per 10C rise in the temperature. It is denoted by the symbol ‘α’. The change in the resistivity of the material with the change in temperature is given as ...
In a circuit, electricity flows through a resistor and into an electric coil. Initially, the coil resists the flow of current to maintain stability. As the current increases, the coil allows more current to pass through. When the current is removed, the coil resists the change and continues ...
A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. Based on the semiconductor material used and the amount of doping, an LED will emit a coloured light at a particular spectral wavelength wh
What is the difference between variable resistor and a resistor in electricity? How does a potential divider circuit work and where is it used in real life? Explain the statement: current is not used up as it flows through a circuit. What is the difference between capacitor and battery? How...
An OBC is used when the battery of an electric vehicle (EV) is charged. It converts power from a charging station into the voltage the battery needs. EVs are expected to further increase in number, and an OBC with a higher power output is absolutely need
