Describe how a battery can create a current in a conducting wire?
The battery produces a voltage; if a conducting wire - or any circuit for that matter - is connected, a current will flow according to Ohm's Law, that is, the current is calculated as voltage / resistance.
What does break resistance means?
Resistivity is the ability of any metal or conductor to resist the flow of current depending on the diameter of the conductor.Electric fuse is an alloy with low resistivity and breaks when the resistance is high.This is the point of break resistance. Literary meaning of break resistance would be an act of greater force to break any opposing force as a breakthrough the defence.
What happens when a battery is hooked up to an open circuit?
nothings because they is no wire connected to the circuit so no current can flow through
How do you convert conductivity to resistivity?
Conductivity is a measure of the ability of a substance to conduct electricity. Resistivity is a measure of how strongly a substance resists the flow of an electric current. So conductivity and resistivity are opposed to each other. A good conductor like copper has a low resistivity, and a good insulator like glass has a low conductivity and a high resistivity. Mathematically, conductivity and resistivity are inverses of each other, so it is quite easy to convert conductivity to resistance.
What is resistivity and what factor does it depend?
Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the movement of electric charge. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is theohm⋅metre (Ω⋅m)It defined as resistance offerde by a unit length and cross section area conductor.It depends on material used.it depends on relexation time and temperature.
What is the current in a 1.5V Alkaline battery?
The current depends on what is connected to the battery's terminals. If nothing is connected to it, then there is no current, and the battery lasts quite a while. In general, the current is 1.5/resistance of the external circuit connected to the battery until that number gets too big, and then the voltage of the battery sags, because it can't deliver that much current.
A 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor What is the current in the circuit?
If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes. If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.
Can a wire connected across a battery's terminal produce current?
Yes
What is the current of a 1.5 volts battery?
That depends on the resistance connected. Use Ohm's Law: V=IR. Solving for current: I = V/R. If nothing is connected, there will be no current (infinite resistance).
What is the electric current from a battery?
A direct current is obtained from a connection to a battery.
When a volumetr is connected in series with a battery what does it measure the ability to?
Measures the amperage of the current .Your battery is in series with your car amp meter .
If voltage is 60V and current is 4A then find resistivity?
There is not enough information to find the resistivity. The resistance can be found by Ohm's law. Just divide the voltage by the current.
Could a wire connected across a battery's terminals produce a current?
sure whatever?
What is the resistance in a discman if it is connected to an 8.6V battery and draws a current of 0.9 Amperes?
I have no idea
When two or more electric cells are connected together as a source of current?
parallel
How much current does a size D battery have?
Doesn't work like that. Current drain is dependent on the (internal resistance of the battery and the) resistance/power requirements of what's connected to the battery. If shorted out, the current - unless the battery is fused or otherwise protected - can go into tens of amps.
