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 volts and a current of 5 amps, this is the resistance.
What is 24 ohms?
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 amps and the resistance is 3 ohms, this is the voltage.
What is 30 volts?
An atom normally has as many electrons as it does protons, so each positive charge is balanced by a negative charge, which leaves the atom uncharged or neutral. This is 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 volts and the resistance is 12 ohms, calculate the current.
What is 2 amps?
This is the build up of charges on an object.
What is static electricity?
A switch is included to control the electric current. Opening or closing the switch breaks the circuit, which shuts off the device.
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 volts. If a light bulb runs a current of 0.5 amps, calculate the resistance of the bulb.
What is 240 ohms?
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 ohms. If a current of 1.2 amps is going through, calculate the voltage applied.
What is 120 volts?
