What would you like to do?

# What is a flaw in a circuit that allows a large current to flow where not wanted called?

# What is the status of a circuit that is complete and unbroken with flowing electric current called?

closed

# Total opposition to current flow in an AC circuit with both resistance and reactance is called?

Impedance.

# What conditions are needed to allow current to flow in the circuit?

The basic requirements are a power source, a closed circuit and some form of resistance on it to work.

# The current flow in a circuit is measured in what?

amperes or A.

# What is a type of circuit where current by passes most resistance and large dangerous currents flow?

A short circuit. In a properly installed system the fuse will blow to prevent a fire.

# What is the current flowing through the circuit?

Amperes or Amps. To find the circuit Amps, you take the circuit volts and divide the number by the resistance value for the circuit. A=V/R

# What happens to the steel cylinder on the circuit breaker if a large current flows through the coil?

I take it you mean the iron (rather than steel) core of the solenoid. If the current reaches the limit set, it is attracted against a spring by the resulting magnetic field cr…eated by the coil around it. The movement trips the switch that cuts the current, and usually stays mechanically latched off until re-set by a local or remote control. (Some circuit-breakers, called auto-reclosers, re-set themselves once the overload has passed. These are typically used on grid transmission-lines.)

# What is a circuit path called that has a break in it preventing current from flowing?

That's an "open" circuit.

# What kind of circuit allows a current to flow through?

Any complete circuit. ==== An electrical circuit.

# Current flow a short circuit?

yes the current can flow through a short circuit but there is no voltage because of the zero resistance hence current through the circuit will be infinite The above is of cour…se a strictly theorethical truth. In the real world, several things limit current. The power source has a finite capacity, sometimes expressed as internal resistance, sometimes in max current, etc. All the wires, connections, and switches also have resistance. At high levels of current like this, even a small resistance will introduce a significant voltage drop. Use Ohms law, and you'll quickly see that with small amounts of resistance, infinite current isn't a real world situation. Likewise there will always be a certain small voltage, otherwise, there could be no current..

# What is required for current to flow in a circuit?

Basically two things You need basically two things: a complete, closed-loop conductive path and an electro-motive force, that is, a voltage. Check out this picture… for a simple circuit containing a battery, two wires, and a light bulb: http://www.bbc.co.uk/schools/ks3bitesize/science/images/sci_dia_52.gif. The wires and bulb complete the conductive path from, and returning to, the battery.

depends whether AC (alternating current/house current) or DC (direct current/i.e. battery powered) electrons flow thru the wires. in DC circuit they all go the same direct…ion. in AC they alternate...
