What is a region of force around an electric charge within which other charges are attracted or repelled?
electric field. a region of force around an electric charge within which other charges attracted or repelled.
What is the effect an electric charge has on other charges in the space around it?
Chapter 20 – Matching, Concentration, and Flashcards
| A | B |
|---|---|
| Electric Field | The effect an electric charge has on other charges in the space around it. |
| Static Electricity | The study of the behavior of electric charges, including how charge is transferred between objects. |
What do like charges do when they are near each other?
Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.
How do you calculate electrical energy transfer?
The electric energy transferred to a resistor in a time period is equal to the electric power multiplied by time, E=Pt, and can also be calculated using E=I2Rt.
What is energy transferred from?
Thermal energy transfers occur in three ways: through conduction, convection, and radiation. When thermal energy is transferred between neighboring molecules that are in contact with one another, this is called conduction.
What causes charges to move through a circuit?
Circuit Closed path through which electrons flow Static electricity Accumulation of electric charges on an object Parallel A circuit with more than one path Resistance Tendency of a material to oppose electron flow Insulator Does not allow electricity to move through it easily Voltage difference Push that causes charges to move Electric field
How are electrons allowed to move through a conductor?
Conductor Allows electrons to move through it easily Circuit Closed path through which electrons flow Static electricity Accumulation of electric charges on an object Parallel A circuit with more than one path Resistance Tendency of a material to oppose electron flow Insulator Does not allow electricity to move through it easily Voltage difference
