Why is a resistor needed to discharge or charge a capacitor in an electric circuit?

A resistor may be used in series charging for current limiting, filtering, or as a signal isolater. Resistors across caps are to discharge them for your safety or equalize voltages across the caps in series filtering circuit.


What is An example of a short circuit?

A short circuit is one that is characterized by extremely low resistance. This will result in the extremely dramatic increase of current. High current will flow until a safety device opens the circuit, or the weakest link in it burns out. And one of the two usually occurs in a moment or two.==Short Circuit happens when the cables of the electrical appliances are worn out or it's not connected properly,a short circuit may occure.A short circuit has a very low resistance that almost all electric current flow through it.It'll affect the operation of the electrical appliances.Owing to the heating effect,the excess electric current would produce a large amount of heat,wihout a fuse or a circuit breaker,a fire may be occured when there's a short circuit.

Which safety devices provides a weak link in a circuit?

A fuse or a circuit breaker is a safety device that provides a weak link in a circuit. When the current exceeds a safe level, the fuse or circuit breaker will break the circuit, preventing damage to the electrical components and reducing the risk of fire.


Why does electrc trip when you plug in tumble dryer?

A common reason for a tripped electrical circuit when plugging in a tumble dryer could be an overload of the circuit. Tumble dryers require a high amount of power to operate, and if the electrical circuit is already stressed with other appliances, it may trip as a safety precaution. It is advisable to have a dedicated circuit for a tumble dryer to prevent tripping.
