Why would you not get an electric current if you hold a piece of wire in your hands?
Because there is no potential difference (voltage) between your hands.
You can observe that easily if you have a voltmeter: Hold one probe in each hand,
and read the voltage between your hands.
The current in the wire is (voltage between the ends of the wire) divided by (resistance of the wire).
If voltage=0, then current=0.
What else can I help you with?
Is arc welding an example of electric current?
No, an example of an electric current would be using a battery to light a lightbulb.
If a copper wire in a working electric circuit is replaced by a piece of rubber tubing will there be a current in the circuit?
No, a rubber tubing is an insulator and will not allow the flow of electric current like a conductor such as copper wire would. Therefore, if the copper wire is replaced by rubber tubing, the circuit will be broken and no current will flow.
What would you expect to conduct an electric current?
the metal
Would increasing the resistance increase electric current?
no
What charge is an electric current?
Electric current is both positive and negative. If there were only one of those it would be an open circuit and it would not work. The particles would be able to flow one way but not the other.
Which instrument would measure an electric current?
A voltmeter or a multi-meter.
When one piece of the pie has the same shape as would be formed by the hands of a clock when it is exactly three o'clock this piece would represent what percentage of the whole pie?
the answer is 25%
If You wrap a wire around a piece of iron. If you slowly increase the strength of an electric current flowing through the wire you would expect .?
The temperature of the wire will increase and eventually like the "straw breaking the camel's back" the wire will fail if you apply enough current. It is like exceeding the current in a fuse, the wire essentially disintegrates.
How much current should be given to mice in Electric Shock experiment?
The amount of current that should be given to mice in Electric Shock experiments would depend on what is being tested
What do you measure with electric current?
Electric current is typically measured in amperes (A), which is the flow of electric charge through a specific point in a circuit over time. This measurement helps determine the amount of electricity being transferred and the rate at which it is flowing in a circuit.
What would happen if you touch an electric eel?
You would feel a shock. Electric eels' bodies generate electricity and can zap you. This can be dangerous if u pick them up with both hands
How can you stop electric current?
An insulative material is one that will stop the conduction of heat. This would be considered a thermal brake and could be a piece of plastic or wood.
