Name 10 components.
Switch, Cell, Battery, Wire, Buzzer, Voltmeter, Ammeter, Resistor, Variable Resistor, Diode
Why is static energy and magnetism similar?
It’s charged and magnetic
What happens to an insulator that gains electrons?
The energy repels
How is the current like in a series circuit?
It’s the same as there’s only one route for it to flow
How is the current like in a parallel circuit
It’s shared between the components.
What is current?
The number of electrons passing per second.
What is the voltage?
Potential difference in energy across a component
How does static electricity work?
Electrons are transferred onto the dome, so the former gets an electrical charge which is passed to us.
What does a cell do?
Stores electric energy
What does a Switch do?
Turns things off and on
What does a battery do?
Stores chemical energy
What does a wire do?
Transports energy from one device to another
What does a buzzer do?
Provides audio
What does a voltmeter do?
Measures voltage
What does an ammeter do?
Measures current
What does a resistor do?
Reduces current flow
What does a variable resistor do?
Control current
What does a diode do?
Flows electric in one direction
