Stick a screwdriver between the 2 wires. This discharges the capacitor

Are 120V and 208V the same?
no 208v is bigger
Why are you not getting 240v between the two hot wires?
Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180° out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires.
How do you get 120v from 220v socket?
You don't, at least, not legally.
If you put a 60W 120V bulb in a 120V lamp that has a transformer for 240V and plug it into a 240V outlet will it work or blow the circuitry?
Off hand no but your explanations are not clear as to who is doing what to whom,,
What are the two most popular operating voltages for residences?
120v and 240v
What does the red dot on the top of a 120V capacitor mean?
Generally it means that the pressure vent has been activated (Bad).
How do you connect ceiling fan used at home to a capacitor?
typically, you don't attach capacitors to ceiling fans ( 120V or 240V ). A capacitor would only be used for one of two reasons. 1. to reduce the noise on the AC in your home or 2. to reduce the spikes to your fan... neither of these make any sense.
If a 120 volt current is protected by a 25 amp circuit breaker What is the largest number of watts an appliance can safely use?
if its a single current its 120v X 25 amp = 3000 watts
The Norelco Reflex Plus 7310XL says it's dual voltage...What does that mean...Does it work overseas?
Dual voltage means it will operate safely with either 110/120V or 220/240V and all you need to operate it overseas is an electric adapter plug.
Can you run your neon sign of 120v 50hz 60hz 0.6a 7.5kv 30mA in an Australian 240v power outlet?
No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V
Example of electric potential?
120v
If house has no electric meter how can you energize 120v circuit with extension cord or portable generator to operate light switchs?
You can energise the circuit by connecting to a neighbour's supply, then they will pay for the energy used. Anything different is classed as theft. An electrician would be needed to do the job safely.
Where can you find a 120V power cable?
You can find a 120V power cable at your local hardware store. Look in the section under extension cords.
What makes a 480 motor with up down and stop 120v switch work?
I think I understand what you are asking. 3-phase motors usually are equipped with a starter or contactor, since all 3 hot wires need to be switched. The control voltage that runs the starters is 120V, because it's safer and also 120V switches and relays are cheaper. You would have a 480-120V transformer (called a control transformer) in the starter box to provide the 120V "control voltage". So the arrangement you describe would have two contactors, with two phases reversed between them. Energize one, and the motor runs forward. Energize the other, and it runs reverse. The switch sends 120V to each of the contactors, which are equipped with 120V coils.
Are 120V and 208V the same?
no 208v is bigger
Can 240V washer run on 120V outlet?
No.
what is the resistance of circuit with 120v and 10A?
12
