Current
V=IR
What is the formula for Ohm's Law?
(voltage [in volts] = current [in amperes] x resistance [in ohms]
Power [in watts]= current [in amperes] x voltage [in volts
Electric Power Equation
What is P=IV?
positive (+) and negative (-) charges
What are the 2 types of electric charges?
a circuit
What is a closed, conducting loop that electric charges flow through continuously called?
the process of providing a pathway to drain excess electrical charge into Earth
What is grounding?
This happens to electrons when you rub a balloon on your hair.
What is "your hair loses electrons and becomes positively charged, while the balloon gains electrons and becomes negatively charged"?
The measure of how much electrical potential energy each electron can gain
What is voltage?
This is the imbalance of electric charge on an object.
What is static charge?
This is a simple circuit composed of a battery, wire, and a bulb with only one path for the electric current to flow
What is a series circuit?
If you were on a metal ladder and a live electrical wire fell on the ladder, this would happen
What is an electric shock?
This is the direction that current flows through a circuit.
What is "from the negative terminal to the positive terminal"?
This is the type of energy batteries use
What are chemical reactions that create chemical energy?
This is how electrical forces act toward each other
What is "unlike (opposite) charges attract and like (same) charges repel"?
This circuit has 2 pathways for the current to flow
What is a parallel circuit?
These are the best conductors of electricity
What are metals like copper, gold, and aluminum?
This is the reason copper wire is used in houses and other buildings
What is "copper wire is a good conductor of electricity and usually will not get hot enough to cause fires"?
The electric resistance of a wire depends on these 2 things.
What is "a wire's length and thickness"?
The highest resistance wire will be thin and long.
This would keep you from getting shocked when working with electricity.
What is an insulator?
This is the definition of electric power.
What is "the rate, or speed, at which electrical energy is changed into other kinds of energy"?
This is what you would feel if you were to experience 0.75 A of electric current
What is heart failure?
These cannot move through solids, but they can move through solutions.
What are ions?
A battery changes chemical energy into this.
What is electric potential energy?
electric discharge
What is "the quick movement of extra charge from one place to another place"?
A computer is plugged into a wall outlet. The power of the computer is 350 watts. The voltage of the wall outlet is 110 V. This is the current the computer is pulling.
What is 3.18 volts?
You have 3 batteries on one parallel circuit. If each battery is a 1.5 V, and the resistance is 1.5 ohms, then this is the current in amperes.
What is a current of 2 amperes?
