To draw the diagram of a given open circuit, comprising at least a battery, resistor, rheostat, key, ammeter and voltmeter, mark the components that are not connected in proper order and correct the circuit and also the circuit diagram. An electric circuit is a conducting path consisting of electric components between the two terminals of a cell or a battery. An electric circuit is set to be an open circuit when no current is drawn from it. If current is drawn from the cell or battery in the circuit, then the circuit is called closed. Madam, can you show us a circuit with components? Sure, diagram is as follows. Let's do an experiment to draw the diagram of a given open circuit, comprising at least a battery, resistor, rheostat, key, ammeter and voltmeter. Mark the components that are not connected in proper order and correct the circuit and also the circuit diagram. Our aim here is to draw the diagram of a given open circuit, comprising at least a battery, resistor, rheostat, key, ammeter and voltmeter. Mark the components that are not connected in proper order and correct the circuit and also the circuit diagram. A path it is required are a battery or battery eliminator of range 0 to 6 volt, a key, a rheostat, a DC ammeter, range 0 to 2 ampere, a DC voltmeter, 0 to 3 volt, resistance wire and connecting wires. Procedure, suppose an open circuit comprising a battery eliminator, a rheostat, key, an ammeter and a voltmeter. Draw a neat and clear circuit diagram for the given open circuit. On checking the circuit and its components, we find that ammeter is connected in parallel in spite of series. Voltmeter is connected in series in spite of parallel. In voltmeter and ammeter, the current is entering from negative terminal in spite of positive terminal. Draw a neat circuit diagram correcting the errors. Rearrange the components of the circuit according to the circuit diagram and then connect them accordingly. Insert the plug in the key and check the reading of the ammeter and voltmeter. Change the resistance by moving the sliding contact and check that the reading of the ammeter and voltmeter is changing accordingly or not. Observation, an open circuit shown in figured voltmeter and ammeter are not connected properly and current enters from negative terminal and leaves from the positive terminal. When voltmeter and ammeter are connected properly, in circuit shown in figured, both shows proper reading and changing their reading in accordance with the change in resistance by the real start. Results, in circuit diagram, the ammeter and the voltmeter are not connected properly. In circuit diagram, the ammeter and the voltmeter are connected properly. Precautions, the insulation from the ends of the connecting wires should be removed by sandpaper. All connections should be neat and tight. Ammeter should be connected in series with the battery and current should enter from its positive terminal and leave from its negative terminal. Voltmeter should be connected in parallel to the points across which the potential has to be measured. Rear start is used here as a variable resistor. Therefore, its sliding terminal and one of its base terminals should be used in the circuit. Sources of error, ammeter and voltmeter may not be connected properly. The current may not enter from positive terminal and leave from negative terminals of the meters. Rear start may not be connected properly. Thank you, Mom, for this knowledgeable experiment.
