Electric Charge & Static Electricity
These are the two types of charges found in an atom.
What are protons, which are positive, and electrons, which are negative?
True or false: Objects that use electricity contain circuits.
What is true?
This type of circuit only has one path for the current to take.
What is a series circuit?
Given a voltage of 120 V and a current of 5 A, this is the resistance.
What is 24 Ω?
a connection that allows current to take an unintended path
What is a short circuit?
This is the interaction between charges.
What is electricity?
Electric circuits are connected with these.
What are conducting wires?
True or false: In a parallel circuit, different parts of the circuit are on separate branches.
What is true?
If the current is 10 A and the resistance is 3 Ω, this is the voltage.
What is 30 V?
Name one way you can resist becoming part of an electrical circuit.
What is: wear rubber soled shoes or avoid being near water with electricity
When an atom has a neutral charge, it has the same number protons and electrons. Explain how an atom can become positively or negatively charged.
What is by gaining or losing electrons?
True or false: Energy is not conserved in circuits.
What is false?
Note, if one light goes out, the other lights will go out too, in a series circuit. If you add a light bulb to a series circuit, the current increases/decreases, causing the bulb to burn brighter/dimmer.
What is: if you add a light bulb to a series circuit, the current decreases, causing the bulb to burn dimmer?
If a battery in a circuit is 24 V and the resistance is 12 Ω, calculate the current.
What is 2 A?
a wire that can divert electricity into the Earth when a short circuit occurs
What is a grounding wire?
This is the build up of charges on an object.
What is static electricity?
A switch is included to control the electric current. This breaks the circuit, which shuts off the device (opening or closing).
What is opening the switch?
In a parallel circuit, if a bulb goes out, what happens to the other bulbs?
What is nothing?
House current is 120 V. If a light bulb runs a current of 0.5 A, calculate the resistance of the bulb.
What is 240 Ω?
Name one way that electricity can be turned off when the circuit is overloaded.
What is a fuse or a circuit breaker?
the loss of static electricity as electrical charges transfer from one object to another
What is static discharge?
All electric circuits have these basic features.
What are: a device that runs on electrical energy, source of electrical energy, and conducting wires?
What happens to the resistance of a parallel circuit when you add a branch?
What is the overall resistance decreases?
A light bulb has a resistance of 100 Ω. If a current of 1.2 A is going through, calculate the voltage applied.
What is 120 V?
If you are outside in a storm, the best way to protect yourself is to stay _________ and _________.
What is low and dry.
