Show hintHide hint
Remember to add the resistances.
Question 2.
Calculate the equivalent resistance of two resistors, 4Ω and 12Ω connected in parallel.
Show hintHide hint
Use the formula for parallel resistances.
3Question 3.
What is the equivalent resistance of 4Ω and 6Ω resistors in series?
- 10Ω
- 24Ω
- 2Ω
Show hintHide hint
Think about the rules for resistors in series.
4Question 4.
True or False: In a parallel connection, the current through each resistor is the same.
- True
- False
Show hintHide hint
Remember how current divides in parallel versus series.
Question 5.
You have three resistors: 5Ω, 10Ω, and 15Ω connected in series. If the total current through the circuit is 2A, what is the voltage across each resistor?
Show hintHide hint
Use Ohm's law for each resistor.
Question 6.
If two resistors, 12Ω and 8Ω, are connected in parallel to a 24V battery, calculate the total current flowing in the circuit.
Show hintHide hint
First find the equivalent resistance and then calculate the current.
