A nickname for something we burn to produce electricity
What are Fossil Fuels?
The two types of electric charge
What are positive and negative?
The base formula of Ohm's Law
What is V = IR?
A circuit has three 2.5 V batteries, and an ammeter reads 0.02 Amps. How much resistance does the circuit face?
What is 375 Ohms
The category of metals that allow the flow of electrons through it
What are conductors?
All generators have this goal in common.
The interaction between two objects with the same charge
What is repel?
If the voltage of a circuit is 12V and the current is measured as 3 A, what would the resistance be?
What is 4 Ohms?
An ammeter reads 13 Amps, but the batteries you have connected are 26 V in total. If the resistors in the circuit are 5 Ohms in total, how much are they off by?
The unit of potential difference
What is volt?
The part of a generator that spins
What is a turbine?
Electrons transfered from objects after rubbing two objects together
What is charging by friction?
What is the voltage of a circuit that has 0.2A current and 500Ω resistance?
The massive transmission lines you see North of Summit Rinks carry 500 kV. If 1kV =1000 Volts, and the current is 10 Amps, what would the resistance be?
What is 50,000 Ohms
If the voltage remains the same, but the resistance doubles, this happens to the current
What is reduced by half?
British Columbia uses these structures to generate electricity
What are hydroelectric dams?
A category of materials that doesn't hold a charge
A circuit has a resistance of 10 Ω and a current of 0.3 A. The voltage would be
What is 3 volts?
The power of the microwave we dissected was 1100 Watts. If P = VI and we plug it into a regular outlet, what is the current?
What is 9.16 Amps?
A current is applied to a circuit. The wires split into two directions. One has a 3 ohm resistor, the other with a 4 ohm resistor. Where do the majority of electrons go through and why?
What is the path of least resistance?
This is a key component of a generator which the Earth has it's own version of
What is a magnet?
Why do clothes stick together after being in the dryer? Must be very specific!
Static charges caused by friction creates an attraction between the opposite charges.
A resistor gets hit with a bunch of voltage and current. In order to stop the massive flow and pressure the resistor converts some of the energy into what?
What is heat energy?
Mr. Craig's car is currently charging on the school charger. Using the formula of P = VI where P= power, V = Voltage, and I = Current. If the P = 5,500 W, and I = 28 A, what is the resistance?
