The transformer turns ratio gives the voltage ratio only for sinewaves, i.e., AC of appropriate frequency. The coil in a car is designed to operate differently. It is supplied with interrupted DC and the high voltage output is defined by the more general induction characteristicNoirro said:Homework Statement
Hey there! I have simple problem:
To start a spark in a car ignition system, voltages of 5-17kV are required. A transformer with winding ratio 1:100 is used with a 12V battery, so we get a 1200V voltage. How are higher voltages achieved in such systems?
Thanks
A transformer is an electrical device that is used to transfer energy between two or more circuits through the principle of electromagnetic induction. It works by changing the voltage and current of an alternating current (AC) electrical supply.
There are two main types of transformers: step-up transformers, which increase the voltage from the primary to the secondary circuit, and step-down transformers, which decrease the voltage. Other types include autotransformers, isolation transformers, and variable transformers.
The main components of a transformer are the primary and secondary windings, which are typically made of copper wire, and the core, which is made of laminated steel. Other components may include cooling systems, insulation, and protective devices.
Transformers are used in a variety of applications, including power distribution, voltage regulation, and electrical isolation. They are also commonly used in electronic devices such as computers, televisions, and audio equipment.
The right transformer for your needs will depend on factors such as the voltage and current requirements of your circuit, the type of load being supplied, and the size and efficiency of the transformer. It is important to consult with a qualified engineer or electrician to determine the best transformer for your specific application.
