Question 1.
What is the current if the voltage is 12V and resistance is 4Ω?
Show hintHide hint
Use I = V/R.
Question 2.
If the voltage across a circuit is 5V and the resistance is 10Ω, what is the current?
Show hintHide hint
Apply Ohm's Law.
3Question 3.
What does Ohm's Law state?
- I = V + R
- I = V/R
- I = R/V
- None of the above
Show hintHide hint
Recall what Ohm's Law formulas can look like.
4Question 4.
True or False: Ohm's Law can be applied to all types of materials.
- True
- False
Show hintHide hint
Think about the limitations of Ohm's Law.
Question 5.
A technician needs to design a circuit that cannot exceed 2 amperes of current. If the available voltage supply is 24V, what resistance must be used?
Show hintHide hint
Rearrange the equation to solve for resistance.
Question 6.
In a complex circuit, if one resistor has a resistance of 10Ω and another has 20Ω combined in series with a voltage of 30V, calculate the total current flowing through the circuit.
Show hintHide hint
Add the resistances together to find the total resistance first.
