It depends on the resistance of the circuit, as V=IR, so I=V/R (V=Voltage, I=Current, R=Resistance)
If a 1.5 volt battery is replaced by a 9 volt battery in a circuit, the current flowing through the circuit will likely increase. This is because the higher voltage of the 9 volt battery will provide more electromotive force, pushing more current through the circuit, assuming the resistance remains the same.
Current will go up by a factor of 6 times in that scenario.
45 Watts
Cars do not have 120 volt batteries. They are 12 volt DC.
3v battery is used direct current
The current output is governed by the load resistance of the circuit. The battery will try and supply as much current as needed up until the battery goes dead.
3 Ampere
The maximum current capacity of a 9-volt DC battery will depend on the specific type and size of the battery. However, for a typical alkaline 9-volt battery, the maximum current output can range from around 500mA to 1000mA. It is important to check the specifications provided by the manufacturer for the exact current rating of the specific battery model.
it needs approximate 8-9 amp current to charge.
V = IR, so if you double the voltage without changing the resistance, the current will also double.
An inverter converts direct current into alternating current. An inexpensive 12 volt inverter is often used to convert 12 volt direct current from a battery to 120 volt alternating current to power small household appliances during a power failure. More expensive inverter systems with large batteries are also available for use with solar panels, wind generators, or other non-commercial power sources.
Depends entirely on how much current you use to charge it.
