current and static electricity

the flow of electrons

how strong the current is in a circuit, difference in electrical potential between two points

resisting the flow of electrons

simple circuit

series circuit

parallel circuit

battery

light

single battery cell

resistor

switch

motor

fuse

ammeter

voltmeter

turn the dial to a, insert black lead into com, and red lead into v, place the ammeter cords in the same way you'd place the wires in the circuit therefore the electrons will flow through the ammeter

turn the dial to v, insert black lead into com, and red lead into v, connect the voltmeter cords in parallel with the black lead first and red lead second

voltage = add up all the voltage values to get sum, current = to each other

voltage = to each other, current = add up all the current values to get the sum

voltage pushes the current through the device

material like copper has a lower resistance, length longer wires have a greater resistance, temperature heating a wire increases it's resistance

when a low resistance path not fit to have electrons flow through it receives a high electrical current

v = ir

like charges repel each other, opposing charges attract each other

keeps electricity in it's material and has a higher resistance for electrons to flow through

low resistance, lets electricity flow through it easily

when two materials cause friction by rubbing together the negatively charged one loses electrons and becomes positively charged and the positively charged material gains electrons and becomes negatively charged
