What reading would you get if a voltmeter is placed in series across a load in closed circuit?
In series and across the load are contradictory statements. Some voltmeters are really capable of voltage, current and resistance measurements. To measure current the meter either has to be a clamp on type or one that goes in series with the load. You measure voltage drop across the load as described above.
What else can I help you with?
When a switch is on is a circuit open or closed?
If the switch is what is keeping the load from turning on, then yes, there is a voltage across the open switch.
Why does an electric circuit have to be closed for it to work?
yes it does have to be a closed circuit
Electricity will flow only if an electrical circuit is?
if an electric circuit has potential difference. Electricity will flow only if an electrical circuit is closed.
What is the antonym of circuit?
The answer would simply be: A closed circuit, un-open path, closed , un openable?? some of thoughs? maybe?
When all parts of a circuit are composed of conducting materials the circuit is said to be?
When all parts of a circuit are composed of conducting materials, the circuit is said to be closed. One condition could be a closed circuit, however it could be open if the components are not assembled or are assembled incorrectly.
Does a food's liquid content affect it's voltage?
I'm sorry, but food is not usually associated with voltage. Voltage, actually electro-motive force, is a measure of the "pressure" of electricity in a circuit. (You can measure EMF in Volts where there is no closed circuit, but the voltmeter itself provides a closed circuit during measurement).
Is the sum of the potential differences equal to the voltage applied across them?
Yes for a closed circuit
Measure the voltage across a voltmeter and a switch?
If the switch is closed (connected) the voltage across it will read 0V. If the switch is open (disconnected) the voltage across it could be anything, it just depends on what the voltage between the wires going into the switch is.
When is a circuit is closed?
When a circuit is not closed it is not operating.
When a circuit is not closed?
When a circuit is not closed it is not operating.
What is another word for closed circuit?
Another word for closed circuit is a loop.
When a light is on it is part of a scolde circuit?
when a light is on it is part of a scolde circuit
When a switch is on is a circuit open or closed?
If the switch is what is keeping the load from turning on, then yes, there is a voltage across the open switch.
Why does an electric circuit have to be closed for it to work?
yes it does have to be a closed circuit
What is required for current to flow through an electrical current?
Potential Source connected across a Closed Circuit Path.
How does closed circuit work?
A closed circuit works by having electricity flow in a complete circuit or circle or any closed shape.
Is voltage measured in series?
ANSWER:Imagine that all the elements of a simple circuit (such as a battery, a light globe , a switch, and a resistor ) When the switch is closed , the electric current flows round and round the circuit just the same way as water would flow through these elements if the circuit had a Water pressure supply and a thin section of pipe and then a thick section of pipe etc . The FLOW of the electricity in Amps can be thought of as the same thing as the Flow rate of water in a pipe system. The Ammeter, is put into the circuit between any 2elements of the circuit, so that the current flows through it , as well as all the other elements (parts) of the circuit. When current flows through the various elements the flow rate (Current) is the same in all of them. As the current flows through, there is a drop of pressure (Voltage) as the electrons flow through each of the elements of the circuit. The actual pressure(volts) in each piece of the circuit , can be measured, by placing a Voltmeter across any individual item in the circuit. The drop in pressure at each item is measured by connecting each terminal of a Voltmeter across the item you are dealing with. The voltage across the 2terminals of the supply will be perhaps 12 Volt(a car battery) The volts ' pressure ' across the globe may be say 8 volt and the volts across the switch may be 3volts and the volts across the resistor may be only 1 volt. Always think of Ampere, as 'Flow Rate', and think of Voltage as ' Electric Pressure' If a circuit has a spot where it splits into 2 separate circuits , and then turns back into 1 piece of circuit, the current flowing as it goes into the 2 different passages, is split up, or shared between the 2 passages, and then the 2 separate currents join together again as they re-enter the single part of the circuit. To find out the current flow in each of the 2 parallel parts of the circuit you must place the Ammeter in series within each of the 2peices of circuit . The 2 separate curent readings will have a total equal to the current reading in the main single passage circuit.
