Watt’s Up?
The term for the "wrong" way current is drawn, flowing positive to negative.
What is conventional current?
This is the "opportunity" for electrons to collide with material and lose energy.
What is resistance?
If you double the distance between two charges, the force becomes this much weaker.
What is four times weaker?
This type of circuit has only one path for the electricity to follow.
What is a series circuit?
These are the two ends of any magnet.
What are north and south poles?
These particles are the actual things moving past a fixed point in a current.
What are electrons?
A circuit with high current but low voltage is generally considered this.
What is not safe to touch?
If the distance between two objects is tripled, the force is reduced by this factor.
What is nine?
This type of circuit has multiple branches or paths.
What is a parallel circuit?
Magnetic forces follow the same "attract/repel" rules as these.
What are electrical charges?
This type of charging occurs when a child slides down a plastic slide.
What is charging by friction?
Metal with high resistance is useful for this room-warming appliance.
What is a space heater?
If you halve the distance between two charges, the force does this.
What is quadruples / increases by four?
Turning on a light switch completes the circuit, making it this type.
What is a closed circuit?
Every magnet must have at least this many poles.
What is two?
Touching a neutral object with a charged object is called this.
What is conduction?
To increase the resistance of a wire, you should make it thinner and this.
What is longer?
Electric force is weakest when the charges are in this relative position.
What is far apart?
In a diagram, the long line on a battery symbol represents this side.
What is the positive side?
This is the area around a magnet where the force can be felt.
What is a magnetic field?
A girl’s hand is negative; the doorknob becomes positive nearby but without contact.
What is induction?
This type of energy is what kinetic energy is converted into by a light bulb’s resistance.
What is light energy?
If you triple the charge of BOTH objects, the force increases by this much.
What is nine times?
In a circuit diagram, we use these types of arrows to show the actual flow of electrons.
What are solid arrows?
If you break a magnet into 100 pieces, each piece will still have these.
What are a north and south pole?
