Ohm's Law
What is the voltage applied on a 25 ohm resistor with a current of 10 amperes?
250 V
This device opens and closes an electric circuit
What is a switch?
Units for voltage
What is volts?
This type of circuit has a single pathway for electricity to flow.
What is a series circuit?
A steady flow of electrons through a circuit is called __________.
What is a current?
Your phone has 1.5 volts flowing through it. If the total resistance is 3.00 ohms, what is the current allowed to travel through?
.5 A
An energy-storage device that serves as a power source
What is a battery
A material capable of transmitting energy in the forms of heat and electricity
What is a conductor?
This circuit forms branches where each path is a separate path for electricity to flow.
What is a parallel circuit?
A conductive path through which an electric current flows
What is a circuit?
What is the current flowing through a flashlight that has a 2 AA batteries (1.5 V each) for a total of 3.00 V and a resistance of 6.00 ohms?
0.5 A
A strand of metal, usually copper, used to conduct an electric current.
What is a wire
A lightbulb functions as this device/component of a circuit.
What is a resistor?
This circuit make a complete path for electrons to travel to travel with no breaks or openings.
What is a closed circuit?
This slows down current in a circuit. It is necessary in all circuits.
What is resistance?
A 120 V wall outlet supplies a TV with a resistance of 2200 ohms. What is the current flowing through the TV?
0.05 A
The device/material in which electricity cannot move through easily.
What is a resistor?
What is Ohm's law?
V = IR
This circuit will not light up the other bulbs if one is out of place or goes out
What is a series circuit?
These are tiny, negatively charged particles
What are electrons?
If voltage is increased across a circuit, what happens to the current?
it increases
This is a device that stores energy so it can be released all at one time.
What is the capacitor?
The symbol for current.
What is "I"
The circuit will continue to light multiple bulbs, even if one bulb goes out.
What is a parallel circuit?
The "electrical push" that creates current provided by the power source.
What is voltage?
