Circuit Training
A closed path that electricity flows through
What is circuit
This is the equation for ohms law
What is V=IR
Draw a series circuit with a battery
---
Two north magnets do this
What is repel
Two types of circuit
What are parallel and series
These are the 3 units in ohms law
These are two types of materials are opposites, one allows the flow of electrons and one opposes
What are conductors and insulators
Where is at the poles
These flow through a closed circuit
What are electrons
If a 20V charge has a resistance of 30 ohms, this is the current?
What is .667A
Draw a parallel circuit with a battery, a light and a switch that switches off the whole circuit
---
Temporary magnet made by placing a piece of metal, like iron, in a current-carrying coil of wire.
Electromagnet
Circuits conduct electricity. This is the definition of conduction
If a 180 V battery has 9 amps of current flowing through it, This is the resistance?
What is 20 ohms
What is fuse or circuit breaker
Two ways of increasing the strength of an electromagnet
increase current
Device that detects electric charge
What is an electroscope
Name two ways that would increase the resistance on a wire
longer wire, thinner wire, hotter wire
Draw a circuit that has a a battery, an ammeter, three lights and a fan and a way to turn each light off and on individually but the fan always has a light on when its on

What is the energy conversion in a generator
KE --> electrical E
