A student builds a series and a parallel circuit. Both circuits contain one battery(of equal voltage) , and two light bulbs. In which circuit should the lightbulbs shine brighter

• series
• parallel
• both will be the same

Batteries, provide ______________________ which is the pressure force that gives electrons the potential energy to move through a circuit

• Voltage
• Power
• Current
• Resistance

Electrical current measures...

• The rate at which charge (electrons) flow or move in an electrical circuit
• The pressure/ energy that pushes electrons through an electrical circuit
• The opposition a material offers to the flow of electric current
• None of the above

In an electrical circuit, if the voltage is constant and the resistance is increased. The electrical current will

• increase
• decrease
• not change

Electrical current is measured in....

• amperes
• volts
• ohms
• newtons

Electrical resistance is measured in...

• ohms
• amperes
• volts
• newtons

Magnetic fields and electric fields are identical in that they both–

• require a medium to travel from place to place.
• influence non-metals the same as metals.
• are capable of exerting force at a distance.
• increase in strength with distance from source.
