If you have two resistors (a 50 Ohm and a 10 Ohm) connected in series to your circuit, which one would have the greater current? They would both have the same current. The ammeter is added within the circuit and the voltmeter has a probe you touch to places in the circuit. Explain the difference between connecting an ammeter versus connecting a voltmeter when using the simulation. If you have two resistors (a 50 Ohm and a 10 Ohm) connected in series to your circuit, which one would have the greater voltage? The 50 Ohm resistor would have the greater voltage. If you have two resistors (a 50 Ohm and a 10 Ohm) connected in parallel to your circuit, which one would have the greater voltage? They would both have the same voltage. If you build a circuit similar to those built in the simulation but with real equipment, how would you determine the resistance of the resistor? Measure the current and voltage and then use Ohm's law. If you have two resistors (both 50 Ohm resistors) connected in series to your circuit, which one would have the greater voltage? They would both have the same voltage. If you have two resistors (a 50 Ohm and a 10 Ohm) connected in parallel to your circuit, which one would have the greater current? The 10 Ohm resistor would have the greater current. If you increase the voltage of the battery, how will the electron displayed by the blue dots change? The blue dots will move faster to show more energy is being used. If you have two resistors (both 50 Ohm resistors) connected in series to your circuit, which one would have the greater current? They would both have the same current. If you have two resistors (both 50 Ohm resistors) connected in parallel to your circuit, which one would have the greater current? They would both have the same current. If 120 volts are used to light a 100-watt light bulb, the current in the bulb will be 100 amps. Electric power is measured in watts The power consumed by an electric light bulb is the product of the voltage across it and the current passing through it. If three light bulbs of different wattage are connected in series to a battery, the current in each light bulb will be the same. How much charge passed through any point in the circuit? 600 C The unit of electric potential is the volt The current through a 10-ohm resistor connected to a 120-V power supply is 12 amps. A steady current of 2.5 A flows in a wire for 4.0 minutes. The unit of electric current is the ampere.

good insulator In conductors, electrons can flow because their electrons are free and mobile. poor conductor A material will be a _ if it does not contain charges that are free to move around within the matter. According to Coulomb's law, if the distance between two charges is doubled, the force each charge exerts on the other will be _ its previous value one fourth of The unit of electrical charge is the coulomb A material will be a _ if it does not contain charges that are free to move around within the matter. An object can acquire an electrical charge by friction, contact, or induction. If you strip electrons from an atom, the atom becomes a positive ion. If you generate a new pulse like the first but more quickly, the pulse would be narrower. Which one of the following is most likely to be impossible? None of the above n 10 What will this wave look like after it reaches the fixed end and reflects? image shows upside down going back towards the starting point If frequency increases, the number of waves increases. What will this wave look like after it reaches the loose end and reflects? The image is flipped to go in the opposite direction it came in Sound is made louder by increasing the amplitude The diagram shows a wave with a fixed end. The diagram shows a wave with a loose end. If you advance a wave one frame at a time, a knot at point A near the top of the wave pulse would be lower. An example of longitudinal waves is/are a slinky spring. When using the kazoos, the sound waves moved through them, and the longer kazoo had a lower pitch. If you start over and move your hand more quickly, the peaks of the waves will be closer together. When a wave strikes a solid barrier, it behaves like a basketball hitting a backboard. An echo is caused by reflection of sound waves. Reflection of sound waves produces the phenomenon known as an echo.

solids liquids gases A piano, violin, or guitar uses the resonance of a wooden soundboard to amplify the sound. In general, sound travels most rapidly in _, less rapidly in _, and even less rapidly in _.
