What is Ohm's Law?
Think about the relationship between voltage and current.
If the voltage is doubled, what happens to the current?
Consider the formula V = IR.
What does Ohm's Law state?
Consider the formula V = IR.
True or False: Ohm's Law applies to all materials.
Think about materials that don't have a linear relationship.
If a circuit has a voltage of 15 volts and the current flowing through it is 3 amperes, what is the resistance of the circuit?
Rearrange the formula from Ohm's Law.
In a certain circuit, if the resistance is increased while the voltage remains constant, what will happen to the current?
Consider how changing R affects I.
