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.
What would we use if we had to measure several feet?
You would use a yardstick if you had to measure several feet.
What tool would you use to measure the air temperature?
You would use a thermometer to measure air temperature.
What unit of measurement would you use to measure a knife?
You would use CM or INCHES to measure a knife
What unit of capacity would you use to measure a bathtub?
you would use gallons to measure the capacity of a bathtub
How do you measure EMF?
Use a voltmeter.
How do you determine the emf and internal resistance of a cell?
You can measure the emf of a cell by using a voltmeter, as this draws current from a cell. You can use the voltage, the emf, and the load resistance to determine the internal resistance of the cell.
Do EMF apps work to accurately measure electromagnetic fields?
EMF apps may not always accurately measure electromagnetic fields. Their effectiveness can vary depending on the app and the device it is used on. It is recommended to use professional equipment for precise measurements.
How do you connect a voltmeter to a battery?
To measure the total emf simply connect the battery and voltmeter with the right terminals , but to measure the terminal potential difference which is less than the emf the voltmeter is connected in parallel with the battery

How to measure the electromotive force (EMF) of a cell accurately?
To measure the electromotive force (EMF) of a cell accurately, use a voltmeter with high precision and connect it to the terminals of the cell. Ensure the cell is not connected to any external circuit during the measurement to prevent errors. Take multiple readings and calculate the average to minimize inaccuracies.
