Resistors and Capacitors

As the resistance of a circuit increases, the current will...

• increase

• decrease

• stay the same

What is the purpose of a resistor?

• allow current flow

• control current flow

• prevent current flow

• allow heat to build up

Which resistor will prevent the most current flow?

• 1 ohm
• 100 ohms
• 1000 ohms
• 0.5k ohms

What is the unit of measurement for resistance?
