How do you want to report the energy? Energy is expressed in Joules. A Joule is a coulomb times the voltage. You will need to do the multiplication.

How much energy is stored in a computer?
If its' unplugged then the only energy would be from the battery which is about 3 Volts.
What is the metric unit of electricity?
There is no "unit of electricity" metric or otherwise. There are units of measurement for electric charge (coulombs), potential (volts), current (amperes), energy (joules) and power (watts).
What is the difference between volts and current?
Electrical current is the number of elementary charge units (coulombs) that pass by a given point in one second. Current, measured in amperes, is coulombs per second. Electrical voltage is the "pressure" behind that current. Voltage, measured in volts, is joules per coulomb.
Can a 220 volts ac fan run in a 12 volts battery?
No. You cannot use any battery for it.
How many volts is an AG10 button battery?
1.5 volts
How much energy does a 12 V battery in your car use to move 2.5 C through the electical circuit?
It takes 31.5 joules for 12 volts to move 2.5 coulombs. Volts is joules per coulomb. The rest is just algebra, i.e. joules is coulombs times volts, 2.5 times 12 is 31.5.
How would you calculate the amperage for a strobe circuit with only the known values of farads volts joules and coulombs?
Amps are coulombs per second, and there is no information on rates given here.
Explain how potential difference in a battery is similar to a staircase?
The potential difference in a battery is like the height of the stairs. The amount of charge separated in a battery is like the mass moved up the stairs. The potential energy in the battery is due to both the potential difference (volts) and the amount of charge that has been separated (coulombs).
How much enegry is available from a 12v storage battery that can transfer a total charge equivalent to 100000C?
The battery can move a charge of 100,000 coulombs through a potential difference of 12 volts, therefore the energy released is 12 x 100,000 coulombs, or 1.2 Megajoules. 100,000 coulombs is (for example) 10 Amps for 10,000 seconds, in other words 10 amps for 2.78 hours, so its capacity is 27.8 ampere-hours.
What is elecromagnetic energy?
Electromagnetic is energy involving electric and magnetic fields. E= VC + IWb where V is volts and C is Coulombs and I is Amperage and Wb is Webers.
How much energy is stored in a computer?
If its' unplugged then the only energy would be from the battery which is about 3 Volts.
How you calculate ups backup time for 4 fan?
For the backup time for 4 fans. First we required battery AH (battery amper) and battery volts & and and ups ratings. then we calculate back time .
How much energy is expended in moving a 20 coulomb charge through a potential difference of 0.5 volts?
To calculate the energy expended in moving a charge through a potential difference, you can use the formula: Energy (E) = Charge (Q) × Potential Difference (V) Given: Charge (Q) = 20 Coulombs Potential Difference (V) = 0.5 Volts Plugging in the values: E = 20 C × 0.5 V E = 10 Joules Therefore, the energy expended in moving a 20 Coulomb charge through a potential difference of 0.5 Volts is 10 Joules.
How do you calculate the charge of a capacitor using random voltage and random time and random resistor?
Battery, resistor, and capacitor are connected in series. E = voltage of the battery, volts R = resistance of the resistor, ohms C = capacitance of the capacitor, farads T = time since the circuit was completed, seconds I = current in the circuit, amperes Vc = voltage across the capacitor, volts Q = charge on the capacitor, coulombs e = base of natural logs = approx 2.7183 At any time 'T' after everything is connected up, Vc = E x (1 - e-T/RC) volts I = (E/R) e-T/RC amperes or I = (E - Vc) / R Q = 1/2 C Vc2 coulombs or Q = 1/2 C E2 (1 - e-T/RC )2 coulombs See ? Nothing to it.
What is 12 volts?
A 12 volt is an amount of electric energy. This type of energy is usually stored inside of a battery.
What is the metric unit of electricity?
There is no "unit of electricity" metric or otherwise. There are units of measurement for electric charge (coulombs), potential (volts), current (amperes), energy (joules) and power (watts).
What is the time duration of a 9 volts battery using 5 volts bulb?
The light-bulb will probably burn out if you connect it directly. Other than that, you CAN'T calculate the time duration based on the data provided. The duration depends on how much energy the light-bulb uses, and how much energy the batter is able to store. Voltage is NOT a unit of energy.
