6 sample questions

Question 1.
What is the current when 9 Volts are applied across a 3 Ohm resistor?
Show hintHide hint
Use Ohm's Law: I = V / R.
Question 2.
How do you calculate resistance using Ohm's Law?
Show hintHide hint
Rearrange the formula I = V / R.
3Question 3.
What does Ohm's Law state?
- Current is proportional to voltage.
- Current is inversely proportional to resistance.
- Both A and B.
Show hintHide hint
Think about how changing voltage affects current.
4Question 4.
True or False: Ohm's Law applies only to resistors.
- True
- False
Show hintHide hint
Consider the broader applications of voltage and current.
Question 5.
A circuit has three resistors in series: 10Ω, 20Ω, and 30Ω, across a 60V source. What is the total current?
Show hintHide hint
First, find total resistance before calculating current.
Question 6.
Calculate the required resistance to ensure that a current of 5A flows when a voltage of 100V is applied.
Show hintHide hint
Rearrange Ohm's Law to solve for resistance.
