Electric Charge and Charging

What is electric charge?

• Electric charge is a fundamental property of matter.

• Electric charge is a type of magnetic field

• Electric charge is a type of battery

• Electric charge is a unit of currency

Explain the process of charging by friction.

• Charging by friction is the process of transferring photons between two objects by rubbing them together.

• Charging by friction is the process of transferring neutrons between two objects by rubbing them together.

• Charging by friction is the process of transferring electrons between two objects by rubbing them together, leading to one object becoming positively charged and the other negatively charged.

• Charging by friction is the process of transferring protons between two objects by rubbing them together.

Describe how charging by conduction works.

• Charging by conduction is a process that requires heating the objects to transfer charge

• Charging by conduction works by transferring charge between objects through direct contact.

• Charging by conduction involves using magnets to transfer charge between objects

• Charging by conduction works by transferring charge wirelessly between objects

How does charging by induction differ from charging by conduction?

• Charging by induction does not require direct contact, while charging by conduction requires direct contact.

• Charging by induction and charging by conduction do not involve any contact.

• Charging by induction and charging by conduction both require direct contact.

• Charging by induction requires direct contact, while charging by conduction does not require direct contact.

What are the two types of electric charges?

• Charged and uncharged

• Positive and negative

• Negative and neutral

• Positive and positive

When two objects are rubbed together and one becomes positively charged, what happens to the other object?

• Becomes positively charged

• Remains neutral

• Attracts neutral charge

• Negatively charged

Can an object be charged by conduction if it is not in direct contact with a charged object?

• Sometimes

• No

• Maybe

• Yes

Explain the concept of grounding in relation to charging by conduction.

• Grounding helps in discharging excess charge by providing a path for the charge to flow into the ground, balancing the charge distribution.

• Grounding increases the charge on an object during conduction

• Grounding has no effect on charge distribution

• Grounding causes charge to flow into the object being charged

What is the role of a grounding rod in charging by induction?

• To attract more charge to the rod

• To store excess charge for later use

• To dissipate excess charge to the ground and ensure safety.

• To repel charge away from the rod

How can you determine the charge of an object using a charged rod?

• Observe the interaction between the charged rod and the object to determine the charge.

• Listen for sounds produced by the object

• Measure the temperature of the object

• Taste the object to determine its charge
