AnswerThe answer is YES! For example, if you connect a capacitor (which comprises two metal 'plates' separated by a dielectric or insulator), in series with an AC supply, then a continuous current will flow. If you connect the capacitor in series with a DC supply, then a current will flow for a short period, before the capacitor becomes fully charged.

∙ 7y agobecause the electrons need a conductive substance to travel though. and air is not conductive (although electricity can go through air at the expense of 10,000 volts.).
a better explanation might be that at the break in the circuit there is an infinitely high value virtual resistance that is made of air (or even a vacuum) that drops, consumes, or dissipates all the available voltage from the supply. the other devices will no longer have a voltage, so, no voltage no current.
you can prove this by measuring the voltage drops across the break in the circuit and across every other device. you will notice that at the break you have the full voltage of the supply and none across any other device in the ckt. If you are using an analog Voltmeter, you might get a slightly less voltage at the break. That's because the ordinary analog voltmeter(not a vtvm) has a characteristic impedance that is effectively in parallel with the break, thus lowering the resistance at that point. A lower resistance will have a lower voltage drop.
in Ohm's Law, there is no open circuit. the "open" is just an illusion. If you think of everything in electronics as just resistance (or resistor) then you can use the formula to find the voltage drops and make your life easier. The formula is Vd = (R1/(R1 + R2)) * Vs for two resistors in series, solving for Voltage dropped (Vd) across R1. if you have more than two resistances in the series string, to find R1 you just add the new resistors at the divisor. if you want to find the Voltage across, say R2, just change the dividend without touching the divisor.

What circuit does not allow electricity to flow through?
An open circuit.
Electricity will flow only if an electrical circuit is?
if an electric circuit has potential difference. Electricity will flow only if an electrical circuit is closed.
What happens to the flow of electricity in an incomplete circuit?
It stops flowing. An analogy to this is the kitchen faucet ... water is always "at the ready" behind the valve, ready to flow when it is enabled. Same is true in an electrical circuit - once the circuit is broken (valve closed in above analogy) the flow of electrons ceases. If there is a light bulb which is not on it is a open circuit. If the light bulb is still on it is parallel circuit which has lot of wires causes some of the lights to go on and some to go of.
Why will a bulb not light if a switch is open in a circuit?
It will not work because it has to be closed so the electricity can go to the bulb.
What stops the flow of electricity?
Turn off the switch, generator runs out of fuel, wind not turning the windmill, solar panel at night, diode, insulation.
Why is an electricity not flow in an open circuit?
The electricity will flow from higher potential to lower potential in a closed circuit.
How can one close an open circuit?
One can close an open circuit by adding a complete loop of wire. This will allow the electricity to flow through the circuit, while electricity will not flow in an open circuit.
What circuit does not allow electricity to flow through?
An open circuit.
Did electricity flow through the wire when the circuit was opened?
Electricity does not flow in an open circut
How does a switch control the flow of electricity?
When the switch is open, the circuit is not a complete circuit. Electricity needs a complete circuit of conductive material. The switch breaks the circuit causing the flow of electricity to be disrupted. When you close the switch, a full circuit is restored thus restoring the flow of electricity.
What is a circuit in which electricity doesn't flow called?
In a lighting circuit an open circuit will turn off the light.
What determines if a circuit is open or closed?
Closed. If it is open then the power is off.
What happens when a circuit has a gap in it?
When a circuit has a gap in it, everythig stops working because the electricity wont be able to flow around the whole circuit
When does electricity flow?
When there is a closed circuit, there is electricity flow.
What happened what happens when a switch in a circuit is open?
it prevents electricity to flow. i hope that is right
What is through a discontinuous circuit which no current can flow?
meaning that the current from your power source doesn't return to the positive end (electricity flows from - negative, to + positive)
Is an open switch in an electrical circuit to prevent current flow?
Yes, an open switch breaks the circuit and prevents electricity flowing through. A closed switch on the other hand completes the circuit and in turn helps electricity travel through the circuit.
