Defined in these scientific terms, 1 volt is equal to 1 joule of electric potential energy per (divided by) 1 coulomb of charge. Thus, a 9-volt battery releases 9 joules of energy for every coulomb of charge moved through a circuit.
Q. Is nC 1 the same as VM 1?
An alternative unit for electric field intensity may be derived as follows. Since Joules = Volts x coulombs = Newtons x metres (J = VC = Nm) we can write NC-1 as [VC/m]C-1 = Vm-1.

Q. What is the unit of E?
Electron charge
Q. What is difference between Volt and Watt?
Watts refer to “real power,” while volt-amperes refer to “apparent power.” Both are simply the product of voltage (V) multiplied by amperage (A). Thus, a device drawing 3 amps at 120 volts would be rated at 360 watts or 360 volt-amperes.
Q. How many watts do I need for ceiling speakers?
For a room 18 feet by 18 feet, with 9-foot ceilings, you’ll want a stereo with at least 25 watts per channel with efficient speakers, or 40 watts per channel with non-efficient speakers.
Q. What is a 70 volt speaker system?
The speakers in a 70-volt system are like houses connected to an electric power transmission line. Each speaker incorporates a transformer that steps down the high voltage to a level that the speaker can handle. The transformer has multiple taps to achieve different wattage levels for the speaker.
Q. How many watts is a 3.7 volt battery?
A 3.7v a 3400mAh 18650 stores about 2 aH to max of 3.5 aH. It can store about 10 to 13 watt hours. A small air conditioning unit that can cool about 9000 BTU uses about 1100 watts per hour. So it would take more than 110 of the 18650 batteries to run the air conditioner for 1 hour.
Q. Which is more powerful volts or Watts?
One of the major difference between volts and watts is that the volt is the SI unit of potential difference and electromotive force, whereas the watt measures the SI unit of power. The measurement taken in volts is easier as compared to watts because watts is the product of the two quantity i.e., voltage and current.
