circuits + currents Flashcards
what is a current
the amount of charge flowing per second
what happens to particles when you complete a circuit
charged particles or charges move in the metal wires
what does the switch dp
- opens and closes a gap in the circuit
- gas must be closed to make a complete circuit for current to flow
electricity is actually
electric current
what pushes charges around the circuit
cell/battery
- it doesn’t produce them they were already in the wires
how do you create an electric field in the wire
when you connect the battery
in a metal what are the charged particles that move called
electrons
how do you measure current through a component
ammeter - connected in the circuit with the component
