Who is Ohm's Law named after?

• Albert Einstein

• George Ohm

• Nikola Tesla

• Isaac Newton

What does Ohm's Law state?

• Voltage equals current times resistance

• Resistance equals voltage divided by current

• Power equals voltage times current

• Current equals voltage divided by resistance

Which component is NOT essential for a basic circuit?

• Switch

• Resistor

• Wires

• Battery

What is the purpose of a resistor in a circuit?

• To store energy

• To provide a path for current

• To generate electricity

• To resist the flow of electricity

What happens in an open circuit?

• The circuit generates more power

• The circuit becomes a parallel circuit

• Electrons cannot pass through

• Electrons complete their loop

In a series circuit, what happens if one resistor fails?

• The entire circuit stops working

• The voltage increases

• The current increases

• The other resistors continue to work

What is a disadvantage of a series circuit?

• Resistors share the voltage

• Each resistor gets full voltage

• It is more complex to design

• It is more expensive

In a parallel circuit, what happens if one path is broken?

• The current increases

• The voltage decreases

• The other paths continue to work

• The entire circuit stops working

What is an advantage of a parallel circuit?

• It is easier to design

• Each component gets the same voltage

• It is cheaper to build

• It uses less power
