Is it possible to have electrical voltage exist but no electric current exist?

Yes. For example, a car battery always has a voltage of 12V (unless it gets completely unloaded, of course), between its terminals. But a current will only flow if cables are connected.

What current does televisions run on?
Electric current, but the voltage required depends on the electrical standards of the country you are in.
What are the three fundamental electrical quantities?
Electric current Electromotive force or voltage Resistance that's all ^^
How you would use the water flow to demonstrate a low-voltage electric current?
In a water system, the "voltage" is the water pressure, the flow rate is the "current", and the pipe size is the "resistance". Low-voltage electrical current is equivalent to low-pressure water.
How is different between voltage and current?
voltage = the electrical "pressure"current = the electrical "movement rate" or "flow rate"
What is the formula of electric current?
the formula for electric current is VI ,where v is voltage then I is the current. the unit used for current is ampere and volts for voltage. multiply the total I to the Voltage The formular of electric current is given by I=V/R ,I=P/V
How do electric compainies usually calculate electrical energy?
They usually just measure current used and assume a known voltage.
What is hall effect hall voltage?
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879
Does electric current increases as voltage increases?
Electrical current generally increases as voltage increases due to a need for increased capacity. This is directly controlled from the transmission side but varies based on the overall load.
What is meant by the terms electric current?
Current is the amount of electrical charge that flows past a given point in a given time. Current is measured in Amperes, which is Coulombs per Second. Sometimes, erroneously, we use the term current to refer to voltage or power. Voltage is Joules per Coulomb. Power is Joules per Second, or Voltage times Current.
What causes a electric current in a electric circuit?
Voltage causes current to flow in an electric circuit.
When does the electric current flow?
An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).
Flow of water and electric current is compared to?
Voltage is what they are compared to.
