Static vs. Current
100: What is static electricity?
Answer : A stationary electric charge that builds up on the surface of objects.
100: What is a positive charge?
Answer: A type of electric charge represented by a plus sign (+).
100: What is the electric force?
Answer: The force of attraction or repulsion between charged objects.
100: How can charges move in a neutral object?
Answer: Charges can redistribute within the object when influenced by a nearby charged object.
100: What is an ammeter?
Answer: A device used to measure electric current in a circuit.
200: What is current electricity?
Answer: A continuous flow of electric charges through a conductor.
200: What is a negative charge?
Answer: A type of electric charge represented by a minus sign (−).
200: What are the effects of electric forces?
Answer: They can push or pull on charged objects from a distance.
200: What happens when a charged object is near a neutral object?
Answer: The neutral object can become polarized, with opposite sides attracting the charged object.
200: What is an advantage of using electric current for heating?
Answer: It can provide a controlled and efficient way to generate heat.
300: How does static electricity differ from current electricity?
Answer: Static electricity does not involve the movement of charges, whereas current electricity involves the flow of charges.
300: What happens when you have equal positive and negative charges?
Answer: The object has a net charge of zero.
300: How does distance affect electric force?
Answer: The electric force decreases as the distance between charged objects increases.
300: How do charges separate when friction occurs?
Answer: Friction can transfer electrons from one object to another, creating a charge imbalance.
300: How can electric charges be used in communication?
Answer: Electric signals are used in devices like telephones and radios to transmit information.
400: What causes sparks when you touch a metal object?
Answer: A sudden discharge of static electricity when there is a difference in electric charge.
400: How do opposite charges interact?
Answer: They attract each other.
400: How do like charges interact?
Answer: They repel each other.
400: What happens to charges in clouds during thunderstorms?
Answer: Positive and negative charges become separated, leading to lightning.
400: Describe how electric eels use electric charge.
Answer: Electric eels can generate electric shocks to stun prey and defend against predators.
500: How do you measure electric current? (hint - device)
Answer: Using an ammeter, which measures the rate of charge flow through a circuit.
Charge is the result of which subatomic particle?
Answer : The Electron
500: What are the three types of electrical current?
Answer: Volts, Watts, Amps
500: Explain how a charged object affects a neutral object.
Answer: It induces charge separation in the neutral object, causing one side to become positively charged and the other negatively charged.
500: Why are some materials better for preventing charge buildup?
Answer: Materials like rubber and plastic resist charge transfer, reducing the buildup of static electricity.
