If you add an ammeter at point B what current would it read when the switch is closed?
All I know about the circuit is that there's a switch in it, and one point in it is labeled
' B ' in the drawing. Get that ? . . . the drawing. By that I mean the picture, figure,
sketch, or schematic that's printed next to the question wherever you copied it from.
With one momentary glance at that picture, all would be revealed and I have no doubt
that I could answer the question. But while the picture remains hidden, even the wisest
among my teachers is helpless and can speak no answer. That may give you some small
idea of how important the picture is.

What instrument can be used to detect electron flow?
An ammeter is commonly used to detect electron flow in a circuit. The ammeter measures the amount of current (flow of electrons) passing through a specific point in the circuit.
Why are the readings on a ammeter always different?
The readings on an ammeter indicate the current being drawn by a load in a circuit. This load is basically a resistance to current flow. The higher the resistance, the lower the current. The supply voltage has a direct effect on current flow. The higher the voltage applied, the higher the current will be. So the readings will vary on the ammeter according to fluctuations in load and or resistance of the circuit and the applied voltage.
What is a circuit called if its operating and the current is flowing?
A closed circuit is one where the current is flowing continuously from the source to the load and back to the source, completing a loop. An open circuit, on the other hand, is one where the current cannot flow because the circuit is broken at some point.
What instrument is used to measure the amount of electricity flowing through a circuit?
An ampermeter. -- voltmeter-- ammeter-- ohmmeter-- wattmeter-- frequency counterWe can't "measure electricity" unless we figure out what we are measuring. The difference of electrical potential is measured in units called volts, and a voltmeter is used to do that. The amount of electrical current flow is measured in units called amps (amperes), and an ammeter is used to for that purpose. A multimeter combines the functions of these two meters, and will most often include some other features to measure some other electrical characteristics. An example of another measuring function of a multimeter might be its use as an ohmmeter for measuring electrical resistance.im so bored
Did San Juan Bautista ever closed?
It is possible that San Juan Bautista has temporarily closed at some point due to various circumstances such as renovations, emergencies, or maintenance. However, as a historic site, its closure status can change, so it is advisable to check the current status before planning a visit.
What will an ammeter show if the circuit is broken?
Zero. No current is flowing in an open circuit. The ammeter will display an amount of 0 amps because there is no longer any current once the circuit has been broken. An ammeter measures current.
How is an ammeter connected in a circuit?
Series connect it within the line of the circuit for which you are interested in measuring the current flow.More detailSince we measure the flow of current IN the circuit, the ammeter must be connected in series with the part of the circuit for which you are interested in measuring the current flow.One of the ammeter's terminals must be connected to a point of the incoming current flow and its second terminal must be connected to the point of on-going current flow. To do this, cut the relevant circuit wire and connect one terminal of the ammeter to each end of the cut.
Where is the best place to put an ammeter in the circuit to measure the current going through the light bulb?
Since (by Kirchoff's current law) the current in a series circuit is the same at every point in the series circuit, it does not matter where you place the ammeter.
How an electric current is measured?
Electric current is typically measured using an ammeter, which is a device connected in series with the circuit. The ammeter measures the flow of electrons passing through a given point in the circuit, usually in units of amperes (A). The ammeter must be placed in series with the circuit to ensure that the current passes through it and can be accurately measured.
What instrument can be used to detect electron flow?
An ammeter is commonly used to detect electron flow in a circuit. The ammeter measures the amount of current (flow of electrons) passing through a specific point in the circuit.
Does an ammeter have a positive and negative terminal?
Yes, an ammeter typically has positive and negative terminals, which are used to indicate the direction of current flow. When connecting an ammeter in a circuit, the positive terminal should be connected to the more positive point in the circuit, while the negative terminal should be connected to the more negative point. This ensures accurate readings of the current flowing through the circuit. However, some ammeters can measure current in either direction without damage, depending on their design.
Why are the readings on a ammeter always different?
The readings on an ammeter indicate the current being drawn by a load in a circuit. This load is basically a resistance to current flow. The higher the resistance, the lower the current. The supply voltage has a direct effect on current flow. The higher the voltage applied, the higher the current will be. So the readings will vary on the ammeter according to fluctuations in load and or resistance of the circuit and the applied voltage.
Can a multimeter be used as substitute of ammeter and voltmeter why?
yes it can read both ac and dc voltage and current .AnswerThe whole point of a multimeter is that it can perform the function of an ammeter, a voltmeter, and an ohmmeter!
When measuring current always place any type of meter in series with the circuit--is this true?
No. While it is true that one can measure current at any point in a circuit by breaking the circuit at that point and inserting the meter, not any meter will do it. One must use an ammeter to measure current.
What does it mean when the circuit is opened?
Its means there is no continuity between point Ato point B. Ex. A light switch : When the switch is off it opens the circuit and electricity does not get to the light, when the switch is on the circuit is closed and the light will turn on.
What are the advantages and disadvantages of crossbar switch?
Disadvantages are : 1.The crossbar switch is singled-layered switch. 2.At each point,there is a switch when closed,connects one of the inputs to one of the outputs.
List two important things to remember when using an ammeter?
Make sure it is placed in the circut series so you can measure the electrical current at a specific point.
