Similarities and differences between the north and pacific ocean currents

1 answer:

4 0

The Pacific is loosely shaped like a triangle, opening widely to the south but barely at all to the north, while the Atlantic is shaped like an hourglass with the choke point located very loosely at the equator (somewhat south of it in the west).

You connect a voltmeter to an unknown resistor in a circuit in order to measure the potential difference across that resistor. H

scZoUnD [109]

Answer:

option (a)

Explanation:

To make a galvanometer into voltmeter, we have to connect a high resistance in series combination.

The voltmeter is connected in parallel combination with teh resistor to find the voltage drop across it.

An ideal voltmeter has very high resistance that means it has a resistance as infinity.

How does changing the potential difference in a circuit affect the current and the resistance?

Effectus [21]

Answer:

The current will be increased and also for the resistance.

Explanation:

The analysis of a direct current circuit can give us the explanation we need. Using the ohm law, which tells us that the voltage is equal to the product of the current by the resistance we have:

$V=I*R\\where\\V= voltage [V]\\I= amperes [amp]\\R=resistance [ohm]\\$

The voltage is equal to the potential difference therefore we will have these expressions:

$I=\frac{V}{R} \\R= \frac{V}{I}$

If we increase the potential differential or circuit voltage, the current will also increase and so does the resistance by increasing the voltage. If we put numerical values in the equation given before, we can confirm this fact.

What type of relationship exists between the length of a wire and the resistance, If all other factors remain the same?

Sergio [31]

Answer: A. Resistance is directly related to length.

Explanation: Resistance is directly proportional to wire length. The longer the wire the greater resistance since there is more space for particles to collide. While resistance is inversely proportional with the cross- sectional area of a wire. The bigger the wire lower resistance.
