This is likely to be caused by the ageing of components, specifically the plastics used for insulation. Dust and humidity will sometimes contribute to it, but not with new components. Some suggest that it is possible to seal the components with black silicon to prevent a repeat. However, the components that are affected carry up to 30000 volts. Not only do they operate at that voltage but they can retain that voltage for days or weeks after the television was last used. Don't under any circumstances try to repair a television unless you are properly trained and qualified to do so.

How does temperature affect the voltage in a series circuit?

If the temperature is changed in a series circuit, the components will get hotter. This increased temperatures in the components then serves to increase the voltage of the circuit.

What are regulatory components?

Regulatory components in short to say they are the components which regulate the input voltage and current applied to the electrical and electronic devices as well as machines also........... In shortly it will stablise the voltage and current and this components are used in stablisers........ It also prevents machines and devices from damage..............

What is a voltage divider circuit?

The voltage divider circuit is a network of two or more components in series, often resistors, between a potential difference. The voltage between the components will be somewhere between the potential difference across the whole network and so divides the total voltage into one or more intermediate voltages.

What are the used of passive components in electronics?

passive components can store the energy in the form of current or voltage , which is useful in electronics circuits.

What is the purpose of voltage regulators?

Voltage regulators are intended to keep a certain voltage level, which is important for most electronics to run properly. Without a voltage regulator, if an electronic, such as a computer, receives too much voltage then it can fry the components.Controls output of alternator so battery does not over or undercharge Should control voltage range from (when engine running) 13.8-14.2 volts Without voltage regulator: Voltage could go to 18-24 volts causing electrical components to burn out

What is total voltage in a series circuits?

In a series circuit the total voltage is the sum of the voltage drops across all the component in series. When the voltage drops across each the individual components are added up, they will equal the supply (or applied) voltage.

How does a current source works?

Basically current sources are made from Voltage sources by adding some extra components to voltage souce.

What is the voltage in which ESD can affect components?

Most components are designed and built to work at very low voltage. ESD can be of a magnitude of 1000 times greater. So if this voltage can find its way into a circuit it can permanently damage the circuit or worst yet weaken it for a premature failure
