Let’s discuss the question: in which circuit would ammeter a show the greatest current. We summarize all relevant answers in section Q&A of website Activegaliano.org in category: Blog Marketing. See more related questions in the comments below.
What is the current measured by ammeter a?
ammeter, instrument for measuring either direct or alternating electric current, in amperes. An ammeter can measure a wide range of current values because at high values only a small portion of the current is directed through the meter mechanism; a shunt in parallel with the meter carries the major portion.
At which position should an ammeter be placed to measure the current passing?
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.
In the above circuit, if the current reading in the ammeter A is 2A, what would be the value of R1?
Images related to the topicIn the above circuit, if the current reading in the ammeter A is 2A, what would be the value of R1?
Which resistor would have the greatest current passing through it?
which resistor has the most current passing through it? the 5-Ω resistor has the most current passing through it, since I = V/R.
How do you find current in a parallel circuit?
Total current in a parallel circuit is the sum of the individual branch currents. This relationship in a parallel circuit is expressed as: IT = I1 + I2 + I3… Whenever more resistances are connected in parallel, they have the effect of reducing the overall circuit resistance.
How is ammeter connected 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. Normally, the ammeter’s resistance is very small compared with the resistances of the devices in the circuit, and so the extra resistance is negligible.
How is ammeter connected in a circuit to measure current flowing through it?
The ammeter is connected through a series connection in a circuit to measure the current flowing through it. An Ammeter is a gadget or instrument that is used in circuitry to quantify the current flowing through it. The current is generated in the circuit which is measured in Amperes.
How is an ammeter connected to a circuit Brainly?
An ammeter is connected in series with the circuit to be measured. The ideal ammeter will have zero resistance so as not to disturb the circuit.
Where should a student hook up an ammeter to measure the current through R1?
In order to measure current through resistor R1, one of its leads must be de-soldered from the circuit board so that the meter may be connected directly in-line (in series) with it.
What is the reading on the ammeter a?
The ammeter is connected in series with the circuit. So its reading will show the value of the current flowing in the circuit. Hence, the reading of the ammeter is equal to 1A. Hence, the voltmeter will show a reading of 2V.
Where is current the greatest in a parallel circuit?
The current is greatest where the resistance is least and the current is least where the resistance is greatest.

Which resistor has the greatest voltage drop?
In series circuits, the resistor with the greatest resistance has the greatest voltage drop. Since the current is everywhere the same within a series circuit, the I value of ΔV = I • R is the same in each of the resistors of a series circuit.
Which circuit contains two or more paths for an electric current to flow through?
A parallel circuit has two or more paths for current to flow through. Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source.
How do you find the current in a circuit?
- To find the Voltage, ( V ) V = I x R ] V (volts) = I (amps) x R (Ω)
- To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)
- To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)
- To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)
How do you find current in a series circuit?
You can calculate the amplitude, in amps or amperes given by the variable A, of the series circuit by summing up the resistance at each resistor in the circuit as R and summing up the voltage drops as V, then solving for I in the equation V = I/R in which V is the voltage of the battery in volts, I is current …
What type of circuit can an ammeter be connected to measure current?
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.
Why ammeter is connected in series with the circuit?
An ammeter is a device which measures the amount of current flowing in a circuit. It is a very low resistance(nearly zero) device. If it will be connected in parallel, it would draw most of the current and would get damaged. Hence, it is connected in series.
How is an ammeter connected in a circuit to measure current flowing through it a series B parallel c either way d none of these?
An ammeter is always connected in series in a circuit because its resistance is very low. So, the correct answer is “Option B”.
What is ammeter how it is connected in a circuit class 10th?
How is it connected in a circuit? Ammeter: An ammeter (ampere + meter) is a device used to measure electric current in a circuit. As shown in Fig, an ammeter is always connected in series in a circuit, so that entire current, which we wish to measure, flows through it.
What are the expected readings of the ammeter and voltmeter

What instrument measures electric current?
The instrument used to measure electric current is an ammeter.
Why must an ohmmeter be connected to a disconnected circuit or component?
Ohmmeters should never be connected to an energized circuit (that is, a circuit with its own source of voltage). Any voltage applied to the test leads of an ohmmeter will invalidate its reading.
