Battery
Convert chemical energy to electrical energy
Ammeter
Measures current strength
Voltmeter
Measures potential difference
Resistor
Resists current flow
Lightbulb
Converts electrical energy to heat and light energy
Rheostat
a variable resistor
Switch
Breaks the circuit is open
Fuse
Protects circuit from excess current
Series circuit
One path to follow the electricity flows through each component
Parallel circuit
More than one path to follow electricity branches to go through components
To maintain a circuit you need…
And I’m broken loop through which the charge can flow and a source of electrical potential energy
Electricity
Flow of charged particles
Electric current
Current is the amount of charge passing a point per unit time
Current strength formula
I=Q/t
One ampere
The amount of current passes appointing a contractor when a charge of one coulomb flows for one second
What does in ammeter measure and how was it connected in a circuit
And ammeter measures current strength and is connected in series
Current is the …….. In series
Same
Current is ………. In parallel circuit
Divided
Potential difference
Potential difference between two points is the work done per-unit charge and moving a positive test charge from one point to another
Voltage formula
V=W/Q
A volt meter measures what and how was it connected in a circuit
Volt meter measures potential difference of voltage and is connected in parallel
Voltages in series………… Equal total voltage
Added
Voltages in parallel are ………. To total voltage
Equal
Resistance
The measure of how difficult it is for electricity to go through a conductor
