Symbols
Write the symbol for voltage
v
If a circuit has 3 2V batteries what is the total voltage?
3x2=6v
Can you run out of nonrenewable resources?
Yes, eventually
Write the symbol for resistance
R
If a circuit has 4 12 resistors, what is the total resistance?
4 * 1 = 4 ohms
True or False: Nonrenewable resources do not consist solely of energy resources.
True
Write the unit and symbol for the unit for current
Amps A
If a circuit has a voltage of 25V and a current of 12, what is the resistance?
V=IR 25=12v R=v/I = 25/12 = 2.08 ohms
Coal, petroleum, and natural gas are fossil fuels are what
Nonrenewable resources
Write the symbol for current
I
If a circuit has 4 6V batteries what is the total voltage?
4x6=24v
What are the costs and benefits of using renewable resources?
reduced pollution and lower carbon emissions, potentially lower long-term energy costs.
what is Ω
ohms
If a circuit has a resistance of 10 ohms and needs a current of 20A to run properly, what should the voltage source be?
V = IR = 20 * 10 -->V-200V
What are the costs and benefits of using nonrenewable resources?
More efficient, more reliable, and easier to transport.
