𝟙.) Use the table to answer the question.
Object Charge (C)
A +1
B +2
C –1
D –2
Assuming other factors are held constant, which two objects will have the strongest attractive force between them?
🅰🅽🆂🆆🅴🆁: Object B and object D
𝟚.) How does the distance between charged objects affect the electric force between them?
🅰🅽🆂🆆🅴🆁: As distance increases, the strength of the force decreases.
𝟛.) Which material would be the best conductor of electricity?
🅰🅽🆂🆆🅴🆁: Copper
𝟜.) Which particles move freely in a conductor?
🅰🅽🆂🆆🅴🆁: Negatively charged electrons
𝟝.) How would increasing the voltage and the resistance affect the electric current in a simple circuit?
🅰🅽🆂🆆🅴🆁: Increasing the voltage would increase the amount of current. Increasing the resistance would decrease the amount of current.
𝟞.) A simple electric circuit has the following properties:
resistance: 12 ohms
voltage: 96 V
Which circuit below has the same current?
🅰🅽🆂🆆🅴🆁: Resistance: 6 ohms Voltage: 48 V
𝟟.) When a hydroelectric dam is operating, falling water moves turbines, which are able to generate an electric current. Which energy transformations are taking place during operation?
🅰🅽🆂🆆🅴🆁: Potential to kinetic to electrical
𝟠.) An electric current moves through a circuit that makes a complete loop. How will the amount of electrical energy change as the current moves through the circuit?
🅰🅽🆂🆆🅴🆁: Electrical energy will decrease if it is converted into other forms, such as heat or mechanical energy.
𝟡.) Which option could be the load of an electric circuit?
🅰🅽🆂🆆🅴🆁: Light bulb
𝟙𝟘.) How does a light switch control a light?
🅰🅽🆂🆆🅴🆁: The switch opens or closes the circuit.
𝟙𝟙.) Use the table of information about three electromagnets to answer the question.
Electromagnet Current Intensity Number of Turns in the Wire
J high 20
K medium 20
L high 45
Which list shows the electromagnets in order from weakest magnetic force to strongest magnetic force?
🅰🅽🆂🆆🅴🆁: K, J, L
𝟙𝟚.) How is an electric field produced?
🅰🅽🆂🆆🅴🆁: When an object has an electric charge
