If you had an isolated ac source (meaning, not connected to Earth ground), like a generator in the back of a pickup truck, for example... you could hold one of the leads from this source with one hand and with the other you could grab hold of the ground rod at your house and you would not receive an electric shock. ...

DON'T TRY IT

lorenb said:So if your generator is producting a voltage (potential energy) higher than that of ground (around 0V). Then you connected these two points there would be a current created between the two.
As mentioned in the other threads about this, the equivalent of capacitance for the battery is huge compared to the voltage, so the amount charge at the terminals is tiny, but it's not zero.Evil Bunny said:If you take a 9V battery and put a volt meter lead on either one of the terminals of the battery and put the other lead into the earth, what voltage do you think you would read?
Charge refers to the amount of electric charge present on an object, while voltage is the measure of the potential difference between two points in an electric field.
Charge and voltage are related through the concept of electric potential energy. Charge creates an electric field, and voltage is the measure of the work done by this field on a unit of charge.
Yes, both charge and voltage can be measured using appropriate instruments. Charge can be measured using an electroscope, while voltage can be measured using a voltmeter.
The SI unit for charge is the Coulomb (C), while the SI unit for voltage is the Volt (V). In practice, micro- and milli- prefixes are often used for both units.
Charge and voltage have a direct relationship, meaning that an increase in charge will result in an increase in voltage and vice versa. This is because charge is the source of voltage in an electric field.
