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 do you connect an ammeter in a circuit?
An ammeter is a measuring device used to measure the electric current in a circuit. A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current.
What does an amp meter tell you?
This type of gauge tells you how much and in which direction the electricity is flowing. This sends electricity through the ammeter to the battery and when everything is running smoothly, the ammeter will show a positive (+) reading.
How is an ohmmeter connected in a circuit?
Ohmmeter, instrument for measuring electrical resistance, which is expressed in ohms. In the simplest ohmmeters, the resistance to be measured may be connected to the instrument in parallel or in series. If in parallel (parallel ohmmeter), the instrument will draw more current as resistance increases.
What should a 12-volt battery read when fully charged?
about 12.6 to 12.8 volts A fully charged battery will typically display a voltmeter reading of about 12.6 to 12.8 volts. If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape. Any voltage above 12.9 volts is a good indicator that your battery has excessive voltage.
How do you read a battery amp meter?
Red and Green Triangles The needle moves to the left, and into the green area. When the battery is fully charged it will indicate around 6 amps. 2 Amp Charging: the small red triangle shows the amps flowing on the 2 amp setting. Again, the needle moves to the left as the battery becomes charged.
What is the rule for current in a series circuit?
Current: The amount of current is the same through any component in a series circuit. Resistance: The total resistance of any series circuit is equal to the sum of the individual resistances. Voltage: The supply voltage in a series circuit is equal to the sum of the individual voltage drops.
Is voltage the same in series?
The sum of the voltages across components in series is equal to the voltage of the supply. The voltages across each of the components in series is in the same proportion as their resistances . This means that if two identical components are connected in series, the supply voltage divides equally across them.
Can you connect an ohmmeter to a live circuit?
Never use an ohmmeter on a live circuit because an ohmmeter is its own power source. You will at best get an inaccurate reading, at worst damage the meter or yourself. Match the meter to the supply. If you are working with DC then use a DC meter; if working with AC then use an AC meter.
Is ohmmeter same as multimeter?
What is the difference between a multimeter, a voltmeter, an ammeter, and an ohmmeter? In modern times, these terms are used interchangeably and all refer to a multimeter. Volt meters measure voltage, amp meters measure amps, ohm meters measure ohms, and multi meters measure a combination of two or more of these.
At what voltage is a 12 volt battery considered dead?
12.0 volts Resting fully charged 12-volt batteries are around 12.8-12.9 volts, and flat dead ones are at 12.0 volts, so 12.4 volts on a resting battery means its about 50% charged.
What are the three rules for a series circuit?
In summary, a series circuit is defined as having only one path through which current can flow. From this definition, three rules of series circuits follow: all components share the same current; resistances add to equal a larger, total resistance; and voltage drops add to equal a larger, total voltage.
Is the current the same in a series circuit?
Current in series circuits The current is the same everywhere in a series circuit. It does not matter where you put the ammeter, it will give you the same reading.
Why the current in series connection is constant?
This is because there is continuity in the charge flowing. There is no accumulation of charge anywhere in the circuit. Hence, since, the electric charge flowing in the series circuit has to remain constant, the electric charge flowing per second in the circuit also has to remain constant.
Notice the voltage drops across each resistor, and how the sum of the voltage drops (1.5 + 5 + 2.5) is equal to the battery (supply) voltage: 9 volts. This is the third principle of series circuits: The supply voltage in a series circuit is equal to the sum of the individual voltage drops.
