3 cards from this section. Quick, good the night before a test.
What is the unit of resistance?
Think of Ohm's Law.
True or False: Conductors have high resistance.
Think about materials like metals.
What is the unit of resistance?
Think about Ohm's Law.
Ohm's Law states that voltage is equal to which two other quantities?
Remember the formula V = I × R.
Design a simple circuit with a battery, resistor, and light bulb. If you increase the resistance by replacing the resistor with one of higher value, what effect will it have on the current and light output?
Relate this back to Ohm's Law.
If a material with high resistance is used in a circuit, what would happen to the power delivered to a device? Explain why.
Think about how current changes with resistance.
