Data: PD=12.0 V
q = 100,000 C
W= ? (need answer in Joule)
Basic Equation: Pd= W/q voltage(PD)=Work(W)/charge(q)
Working Equation: W=PD(q)
Substitution: W= 12.0 V(100,000 C)
W= 1,200,000 J

A fully charged battery which is still on charge (alternator running or 117 volt powered charger connected, for example) could be delivering 15 joules per ampere, or even a little more. An older battery, starting a cold engine, could drop to 6 volts, thus 6 joules per amp. Batteries can go down to near zero under load, but below about 6 volts, the engine is not likely to start. Keep in mind that the joule is a coulomb-volt, a unit of energy. So we are getting a coulomb per volt-amp every second. This is an energy (a rate) of 1 watt per volt-amp. So 100 amps at 10 volts would be 1000 watts. This is doable by a good, charged, lead-acid battery. This would be 1000 joules every second. On a really cold day, we might get 250 amps at 8 volts for 2000 watts. This is 2.68 horsepower and should start our car.

∙ 10y agoWelll ... they don't actually flow 'through' the battery. It's much more
common to talk about the coulombs that flow through the external circuit,
and the energy they give up along the trip.
Each coulomb of charge that flows out of one terminal of a 12v battery,
then through an external circuit and back into the other terminal, yields
12 joules of energy.
1 volt = 1 joule per coulomb

How much energy is supplied to each coulomb of charge that flows through a 12 v battery?
12 watts or 12 joules of energy.In one second, 1 coulomb is 1 amp, so the power is 1 amp x 12 volts = 12 watts, and in that one second, that is 12 Joules of energy.
How many joules of energy does each coulomb of charge have at the battery terminals?
That depends on the voltage. In general, a coulomb of charge will either gain or lose (depending on the direction) one joule of energy for every volt of potential difference. For example, if the battery has 12 V, a coulomb of charge will gain or lose 12 joules of energy when going from one terminal to the other.
How much energy is given to each coulomb of charge passing through 6V battery?
<p><p> Voltage = 6 V Charge = 1 C Current * Time = Charge V * t = Q Energy = Current * Voltage * Time E = VIt E = Q * V E = 1 C * 6 V E = 6 Joules Therefore energy given to each coulomb of chare passing through 6 V battery is 6 Joules . Cheers !
What is the charge in 1 coulomb?
The amount of charge in 1 Coulomb is exactly 1 Coulomb of charge. That's true whether the charge is positive or negative.
Which is bigger a coulomb or charge if an electron?
A coulomb is bigger. Please also note that a coulomb is defined as a POSITIVE charge, while an electron has a NEGATIVE charge. Anyway, the magnitude of a coulomb is much bigger than that of an electron.
How much energy given to each coulomb of charge passing through a 6 volt battery?
The potential difference ('voltage') is equal to the work done per unit charge, i.e. the energy given to each Coulomb of charge. So, a six Volt battery provides six Joules of energy to each Coulomb of charge.
What unit is represented by a joule per coulomb?
A joule/coulomb is represented by the volt. Example: a 9v battery provides 9 joules of energy to every coulomb of charge that passes through it.
How much energy is supplied to each coulomb of charge that flows through a 12 v battery?
12 watts or 12 joules of energy.In one second, 1 coulomb is 1 amp, so the power is 1 amp x 12 volts = 12 watts, and in that one second, that is 12 Joules of energy.
How much energy is given to each coulomb of charge that flows through a 1.5 volt battery?
1.5 volts means 1.5 joules/coloumb.
What does a coulomb measure?
A coulomb is a unit of electrical charge. It is the charge that passes a point in an electrical circuit in one second when a current of 1 ampere is flowing through the point.

What is bigger- a coulomb or charge on an electron?
One Coulomb is the charge of about 6,241,510,000,000,000,000 electrons, so it looks likea Coulomb would probably be bigger than the charge on one electron.
What is dimensional formula of coulomb?
The Coulomb is a unit of electric charge. [Charge] is a fundamental quantity.
Which is bigger a coulomb or charge if an electron?
A coulomb is bigger. Please also note that a coulomb is defined as a POSITIVE charge, while an electron has a NEGATIVE charge. Anyway, the magnitude of a coulomb is much bigger than that of an electron.
How does a coulomb of charge compares with the charge of a single electron?
the charge of 1 coulomb is the charge associated with 6.25 billion billion electrons
