What is needed for an electric current to flow in a circuit?
Three things are needed for an electric current to flow in a circuit: the battery must be connected correctly. One wire must be connected to the (+) positive terminal of the battery and the other wire must be connected to the negative (-) terminal of the battery We use circuit diagrams to represent electrical circuits.
What happens if a battery reduces OCV and R_Batt?
IMPORTANT: The reduction of OCV and/or the increase of R_batt cause the reduction of the fault current provided by the battery. Example: For the VRLA type battery close to the End of Discharge (EOD) and End of Life (EOL), due the OCV reduction and resistance increase, the short circuit current can be around 60% of the nominal short circuit current.
How much power does an AA battery need?
AA batteries typically provide a nominal voltage of 1.5 volts. A device’s power requirement can be expressed as watts, which is the product of voltage and current (watts = volts x amps). When a device requires more power, it increases the current flow needed from the battery.
Does a DC rated circuit breaker provide overcurrent protection?
The DC rated Circuit Breaker still provides overcurrent protection, if correctly coordinated, even though its intervention time can be not enough to avoid extensive damages on the equipment and on the battery.
How a battery protection device should be sized?
A protection device must be sized properly so that the energy flowing from the batteries during the failure will not cause damage to the batteries or other components along the short circuit path. The protection must clear the fault in less than 100 milliseconds. The impedance of the line is mainly resistance and inductance.
How much current does an AA battery deliver?
An AA battery usually has a capacity of 2 ampere-hours. It can deliver a peak current of more than 2 amperes (A). A fully charged AA battery has a voltage of about 1.5 volts (V). As it discharges, the voltage drops to around 0.9 V. Therefore, the current flowing depends on the load connected to the battery.
