## What will happen if we interchange the position of voltmeter and ammeter?

The voltmeter is a high resistance device used to measure voltage across two point and it is always connected in parallel with the the circuit. If the positions of these two are interchanged, the ammeter will be destroyed by high amount of current given that it is of low resistance.

## Does the location of the ammeter affect the current?

Answer: To measure the total current, the ammeter must be placed at position 1, as all the current in the circuit must pass through this wire, and ammeters are always connected in series.

What should happen if you connect the ammeter in the opposite way?

If you connect the wires in an opposite orientation, the needle will go below zero as it attempts to show the direction as well. So, no. Neither the Ammeter or the Voltmeter has a polarity. Hope it helps!!!

What will happen if you will place an ammeter directly across the terminals of a voltage source?

At the very least, placing an ammeter directly across the terminals of a voltage source will likely result in the ammeter’s fuse being blown.

### What would be wrong with the connection if the ammeter deflected in the opposite direction during the experiment?

If deflection takes place in opposite direction, the device is not properly connected in the circuit. We must interchange the terminal connection, so that devices can be used properly in the circuit.

### What happens to the reading when the terminals of the voltmeter were interchanged?

When a voltmeter current is reversed, it will read the load’s voltage polarity in reverse. This means that in a digital voltmeter reading a DC…

What effect does an ammeter have on a circuit?

Just like voltmeters, ammeters tend to influence the amount of current in the circuits they’re connected to. However, unlike the ideal voltmeter, the ideal ammeter has zero internal resistance, so as to drop as little voltage as possible as current flows through it.

Where do you place an ammeter in a circuit?

An ammeter is placed in series in the branch of the circuit being measured, so that its resistance adds to that branch.

## What will happen if polarity of ammeter is reversed 1 point?

Both ammeter and voltmeter which measure DC quantity have polarity, while in case of AC condition polarity is not required. If the polarities are reversed, ammeter and voltmeter show deflection in a negative direction (downscale).

## Why negative terminal of ammeter is connected to negative terminal of battery?

An ammeter is connected in series with the battery. You could connect one probe of the ammeter to the negative post on the battery and the other to the heavy negative connector of the ground or negative cable that you disconnect from the battery. All the current travels through the ammeter.
