When a voltmeter is connected across a cell, it measures the potential difference, or voltage, between the two terminals of the cell. This reading indicates the electromotive force (emf) generated by the cell, which is a measure of the cell's ability to provide electrical energy to a circuit.

How can a voltmeter be connected in series to measure the voltage across a component in an electrical circuit?
To measure the voltage across a component in an electrical circuit, a voltmeter can be connected in series by placing the voltmeter in the same path as the component. This allows the voltmeter to measure the voltage drop across the component accurately.
How can a voltmeter be used to measure the voltage across each component in a parallel circuit?
A voltmeter can be connected in parallel with each component in a parallel circuit to measure the voltage across that specific component. By connecting the voltmeter in parallel, it allows the voltmeter to measure the voltage drop across the component without affecting the overall circuit.
How can a voltmeter be connected in parallel to a circuit to measure the voltage across a specific component?
To measure the voltage across a specific component in a circuit using a voltmeter, you would connect the voltmeter in parallel with the component. This means connecting the positive lead of the voltmeter to the point before the component and the negative lead to the point after the component. This allows the voltmeter to measure the voltage difference across the component accurately.
How can a voltmeter be connected in a circuit, either in series or parallel, to measure the voltage across a component accurately?
A voltmeter can be connected in parallel to measure the voltage across a component accurately. This means connecting the voltmeter in a separate branch of the circuit, directly across the component being measured. This allows the voltmeter to measure the voltage without affecting the current flow in the circuit.
How can a voltmeter be connected in parallel to measure the voltage across a circuit component?
To measure the voltage across a circuit component using a voltmeter, you would connect the voltmeter in parallel with the component. This means that you would connect one lead of the voltmeter to one end of the component and the other lead to the other end. This allows the voltmeter to measure the voltage difference between the two points, giving you the voltage across the component.
Why cant you use voltmeter 2 calculate emf of a cell?
A voltmeter measures potential difference across a component, which may not necessarily be equal to the EMF of a cell due to internal resistance in the cell and voltage drops across other components in the circuit. To accurately measure the EMF of a cell, a potentiometer or a high-resistance voltmeter is used in conjunction with a null point method.

How should a voltmeter be connected to measure voltage of a component?
Since voltage is electrical potential difference, to measure the voltage across a component, you place the voltmeter across, or in parallel with, the component.
Can you measure the pd across pn junction by a simple voltmeter?
Yes.
Why is the voltmeter is placed across the load to be measured?
Because that is what you are trying to measure.
Which will normally have the larger resistance a voltmeter or an ammeter?
A voltmeter has the large resistance.The voltage across any component can be measured if & only if the terminals of that component will be open and this will we can acheiv if we connect the high resistance voltmeter across the open terminals of that component to measure the voltage.
How should voltmeter be connected to measure the potential difference across a resistor - in series or in parallel?
In parallel.
How do you connect a voltmeter in parallel circuit?
A voltmeter is used to measure potential difference across two points in an electrical circuit . The voltmeter is connected in parallel across the circuit element (resistance ) so that its inclusion in the circuit has negligible effect on total resistance and current flowing in yhe circuit A voltmeter has high resistance,if connected in series it will increase of circuit and reduce the current in the circuit
