# Question: Where do I connect my amp meter?

Contents

Connect the positive probe of the ammeter to the positive terminal of the power supply. Connect the negative probe of the ammeter to one end of a resistor. Finally connect the other end of the resistor to the negative terminal of the power supply.

## Where should I place my amp meter?

An ammeter is placed in series in the branch of the circuit being measured, so that its resistance adds to that branch. Normally, the ammeters resistance is very small compared with the resistances of the devices in the circuit, and so the extra resistance is negligible.

## What is the proper way to connect an ammeter?

An ammeter is connected in series while a voltmeter is connected in parallel.

## Does it matter where you place an ammeter?

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. To measure the total voltage in the circuit, the voltmeter could be placed at either position 3 or position 4.

## What is required for an electric charge to flow through a wire?

To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. The pathway to carry the charges is usually a copper wire.

## What happens if an ammeter is connected in parallel with a resistor?

Ammeter aims at measuring the current flowing through the circuit and hence, it is connected in series. When ammeter is connected in parallel to the circuit, net resistance of the circuit decreases. Hence more current is drawn from the battery, which damages the ammeter.

## What happens if you connect the ammeter in parallel to the bulb?

If we connect an ammeter in parallel there will be higher flow of current through the ammeter, it would cause a short circuit, resulting in damaging the ammeter and the circuit. Answer: Ammeter is connected in series always. Ammeter has a very low resistance.

## What is designed to be connected to a circuit in parallel?

Parallel circuits are circuits in which the charges leaving the potential source have different paths they can follow to get back to the source. In the design of this parallel circuit, each resistor (light bulb) is connected across the battery as if the other two resistors were not present.

## Which statement is true for a series circuit?

In a series circuit, all devices are constrained to a single flow of current. There can only be a single value for the current for all devices, otherwise this would violate the conservation of charge. Therefore the current must be the same across each resistor.

## How are current and resistance related?

The relationship between current, voltage and resistance is expressed by Ohms Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.
