corroded/dirty connections
A good conductor for a closed circuit would be a material that allows for the flow of electric current without significant resistance, such as copper or aluminum. These materials are chosen for their ability to efficiently carry electrical energy from a power source to the desired electrical components.
In an open circuit no cuttent can flow so the switch would have to be in the off position- the switch is open and not completing the circuit. A closed circuit is one where current can flow all the way through, the switch would have to on and therefore closed.
An electric circuit needs to be a closed circuit in order for the current to continuously flow from the power source through the electrical components and back to the source. An open circuit, where there is a break in the circuit, would prevent the flow of electricity and disrupt the operation of the circuit.
I assume you mean Voltage, Current and Resistance. Voltage (E)or electromagnetic force is the electrical pressure or force that forces the electrons through any given circuit Current (I)is the flow of those electrons through any given circuit Resistance (R) is anything within the circuit that would restrict the flow of electrons
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
You would have to specify the circuit.
There is no particular benefit for having a higher open-circuit (or 'no-load') voltage. In fact, an ideal voltage source would have no internal resistance and, therefore, its open-circuit voltage would be identical to its closed-circuit voltage.
It could act as one when the circuit is closed, but when the circuit is open, I believe you would define the air as the thing resisting current. In basic circuit problems the switch usually doesn't have any resistance of its own (ie as negligible as the resistance in a wire, so it is ignored).
A simple circuit containing a light switch in the on position is a closed circuit. In a closed circuit, electrical current can flow freely, allowing the light to illuminate. If the switch were in the off position, it would create an open circuit, interrupting the flow of electricity and turning the light off.
A multimeter is an instrument commonly used to measure the properties of an electrical circuit. It can measure properties such as voltage, current, and resistance in the circuit. Multimeters are versatile tools that are essential for troubleshooting and testing electrical systems.
Which would be better in lighting a house a closed or an open circuit ?\
An example of a closed electrical circuit would be a battery to a light bulb, the only source of power being the battery and no other input from an outside source. Like video cameras in a store they would be considered a closed circuit surveillance system so long as the signals stay inside the store and don't leave to a remote location.
