What is the equation that relates voltage and potential energy in an electrical system?
The equation that relates voltage and potential energy in an electrical system is V W/q, where V is the voltage, W is the potential energy, and q is the charge.
What is the equation that relates voltage and electric field in a given system?
The equation that relates voltage (V) and electric field (E) in a given system is V E d, where V is the voltage, E is the electric field, and d is the distance between the points where the voltage is measured.
What two factors determine the output energy of a battery?
The energy delivered by a battery would depend on-- the battery's voltage-- the resistance of the load connected across its output terminals-- the length of the time the load is connectedThe power delivered by the battery is [ (voltage)2 divided by (load resistance) ].The total energy delivered by the battery is [ (power) multiplied by (time the load is connected) ].
How many ampere in a 12V battery?
The amperage of a 12V battery depends on its capacity, which is measured in ampere-hours (Ah). To calculate the amperage, you would divide the capacity (Ah) by the voltage (V). For example, a 12V battery with a capacity of 100Ah would have an amperage of 8.33A (100Ah / 12V).
What is the equation for calculating the energy stored in a battery?
The equation for calculating the energy stored in a battery is E V Q, where E represents the energy in joules, V is the voltage of the battery in volts, and Q is the charge stored in the battery in coulombs.

What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
What is voltage capacity of a alkaline d battery?
About 1.5 volts.

Is a 12v car battery the same as a 12v lantern battery?
Voltage is the same but amp hour capacity of the car battery is much higher.

What is the Formula you can use to find the capacity of a laptop battery?
Wattage = Outage Voltage + Outage Wattage
Why does a short circuit drain a battery?
You have to remember ohms law Voltage = amp * resistance. Using some basic algebra you can rewrite the equation as amps = voltage / resistance. Since a short circuit has relatively 0 ohms of resistance, this increases both the amps and resistance which uses more battery capacity,power, and creates more heat.
How long would a 74 amp battery last connected to a 20watt appliance?
You haven't mentioned the voltage or the Amp-hour capacity of the battery. In order to estimate the life of the battery, we need to know both of those, and we also need to be assured that the battery voltage is the same as the designed operating voltage of the appliance.
How long does a laptops battery last?
it depends on the capacity and voltage of the battery, generally speaking, there are 4-cells, 6-cells and 9-cells batteries on the market, the bigger capacity and voltage will have a longer last time
