Electric current

Choose the correct form of energy

• Sound energy

• Gravitational potential energy

• Sun energy

• Light energy

The following are the source of energy from renewable enery.

• Wind

• Geothermal

• Radioactive

• Biomass

Electrostatic force is

• the attraction and repulsion between electric charges

• An object with more positive charge

• An object with more negative charge

• the negative and positive charge produce by an object

Choose the correct statement about electrostatic

• The positive charged move to electron to form current.

• The number of protons is more than the electron become positively charged.

• The number of electrons is more than the proton become negatively charged

• The number of protons and electrons is equal become neutral.

The device show in the diagram is

• Galvanometer

• Ammeter

• Electroscope

• Voltmeter

The best examples of electrostatic in daily life are

• Lightning

• Electrical appliances
