Question

If we join the two terminals of a battery with a rubber wire a current is produced.

True

False

The electric resistance R in a circuit is meassured in units of:

Amperes

Ohms

Volts

None of the above

The internal resistance of a Voltmeter should be very large.

True

False

When we join the two terminals of a battery by a conducting wire, the electric current will be higher for a higher voltage.

True

False

Amperes

Ohms

Volts

None of the above

The internal resistance of a Voltmeter should be very large.

True

False

When we join the two terminals of a battery by a conducting wire, the electric current will be higher for a higher voltage.

True

False

Explanation / Answer

1)

False, Because ruber is an Insulator.

2)

The electric resistance R in a circuit is meassured in units of Ohms

3)

True, Because voltameter measure the voltage difference between two different points but it should not change the amount of current going through the elements between those two points, so it should have very high resistance so that is doesn't draw current through it.

4)

True, Because current passes through the conducting wire.
