What else can I help you with?
What would the current flow be if a short circuit is put across the battery's terminals?
That will depend on the internal resistance of the battery. I = E / R Where I is the current, E is the open circuit battery voltage, and R is the internal resistance of the battery.
Describe the response of a capacitor when connected to and then disconnected from a battery?
A capacitor that is suddenly connected to a battery will charge to the battery voltage. The time to do this is dependent on the current capacity of the battery and wiring, and the capacitance of the capacitor. This represents an instantaneous short circuit, which lasts for a (usually) very short time - but damage could be done if there was no resistance. A charged capacitor that is suddenly disconnected from a battery will hold that voltage. The length of time it will hold is dependent on how much leakage current there is.
What jobs dose a battery do in the circuit?
The purpose of the battery in a circuit is to wive energy to the circuit
Can a short circuit current through a photo cell damage it?
If the photo cell was on during the short circuit then the chances of damage to the photo cell are at a minimum. If the short circuit occurred when the photo cell was operated then yes damage to the internal contacts of the photo cell could have happened. What happens is, the short circuit is downstream from the photo cell and when the contacts of the relay close in the photo cell the dead short is applied to the contact faces of the relay. This is somewhat like striking an arc with a welded with the same results, the contact faces weld close and the circuits breaker trips to open the short circuit. With the pole faces of the photo cell's relay closed it gives the illusion that the photo cell is not operating. The photo cell's circuitry will be working but the relay will not drop the circuit open because of the welded contact in the relay.
What 2 voltages is a short circuit made of?
Circuits are not made of voltages, they are made of loops. A short circuit exists when a connection is added that is not supposed to be part of the intended circuit as designed. This added connection produces extra loops in the circuit that typically prevent current from reaching parts of the circuit where it is needed and can cause excessive current to flow in other parts of the circuit, resulting in damage to the components in the circuit.
Can Battery shorted by pouring distilled water on it?
Yes, pouring distilled water on a battery can cause it to short circuit. Water is a conductor of electricity, so it can create a path for the current to flow where it shouldn't, leading to a short circuit. This can damage the battery and potentially cause it to overheat or leak.
What happens if a AA battery gets wet?
If an AA battery gets wet, it can cause the battery to short circuit, leak, or corrode. This can damage the battery and potentially cause it to stop working. It is important to properly dry the battery and the device it is in to prevent any further damage.
Should a battery spark when connecting it to a device?
No, a battery should not spark when connecting it to a device. Sparks could indicate a short circuit or improper connection, which can be dangerous and potentially damage the device or the battery.
Should the battery spark when connecting it to a device?
No, the battery should not spark when connecting it to a device. Sparks could indicate a short circuit or improper connection, which can be dangerous and potentially damage the device or the battery.
What is the difference between short to Battery and Open Load?
Related to a battery and open load is the battery just sitting there without anything connected. A short is a very low resistance attached to the tow terminals of the battery. For example, a wire connected across the battery terminals would constitute a short.
Can ice hurt a phone battery?
Yes, it can get the battery wet and short circuit it.
What would happen to the current once a short circuit occur?
Since load current is determined by dividing the supply voltage by the resistance (for d.c., or impedance for a.c.) of the load, a short circuit would theoretically result in an infinite supply current. This is because a short circuit has, theoretically, zero resistance. In practice, however, the current would be cut off by the operation of an overcurrent protective device -such as a fuse or circuit breaker- which would disconnect the short circuit from the supply voltage. A worst-case scenario could occur should you short-circuit a car battery with, say, a spanner (wrench). With no fuse to protect the battery, the resulting short-circuit current, if sustained, may be high enough to cause catastrophic damage to the battery.
What happens if the battery terminals touch each other?
If the battery terminals touch each other, it can cause a short circuit. This can lead to overheating, damage to the battery, and potentially a fire or explosion. It is important to always keep the battery terminals separate to prevent this from happening.
How can short circuit damage devices?
A short circuit can damage devices by allowing an excessive current to flow through the circuit, which can generate heat and potentially cause components to overheat or burn out. This can lead to damage to the device's components or even start a fire.
What causes a short circuits?
-circuit damage -overheating -fire or explosion causes a short circuit.
What causes gasses in a battery?
Overcharging (bad voltage regulator) or a short circuit inside the battery.
How does a short circuit breaker work to prevent electrical fires and protect the circuit from damage?
A short circuit breaker works by detecting abnormal levels of electrical current in a circuit. When it senses a short circuit or overload, it quickly interrupts the flow of electricity to prevent overheating and potential fires. This helps protect the circuit and connected devices from damage.
