Answer the following question given this paragraph: 

The transfer of electrons from the van de Graaff generator to the man is an example of conduction. Conduction occurs when there is direct contact between materials that differ in their ability to give up or accept electrons. A van de Graff generator produces a negative charge on its dome, so it tends to give up electrons. Human hands are positively charged, so they tend to accept electrons. Therefore, electrons flow from the dome to the man’s hand when they are in contact.


Q: A van de graff generator produces what type of charge on its dome, causing the tendency to give up electrons?


A:
negative charge
