Draw a diagram to show how a galvanometer can be converted into a voltmeter. - Leaving Cert Physics - Question 7 - 2008

To convert a galvanometer into a voltmeter, it must be connected in series with a large resistance (often called a multiplier or resistor). The diagram should depict the following:

1. Draw the symbol for a galvanometer, which typically looks like a circle with a 'G' in it or a series of parallel lines representing the coil.

2. Next to the galvanometer, sketch a large resistor in series. Indicate this clearly by labeling it as 'R' or 'Multiplier'.

3. Add two terminals to the diagram to show where the input voltage will be connected.

4. Ensure to include arrows indicating the current direction through the galvanometer and resistor series combination.

This setup allows the galvanometer to measure high voltages without exceeding its current rating.
