YOUR MISSION, SHOULD YOU CHOOSE TO ACCEPT IT, is to connect 4 DIFFERENT resistors in such a way that the total resistance of the circuit is the smallest possible. You must then connect a battery and allow current to flow through each resistor.
• Your secret report must include proof of the current and voltage of each resistor as
• well as proof of the total voltage, current and resistance. A map of the circuit board will be essential as well.
This will greatly aid in restoring the balance of world power and determining your term grade.
Write a complete lab report that includes: aim materials procedure circuit diagram calculations a conclusion indicating the calculated resistance of each resistor
Secret Code: V= IR , R = V/I...... Good Luck

The document that requires the student to prepare a circuit using the smallest resistance possible is asking for a parallel circuit set-up using 4 resistors. Students need to use one of each of the resistors on the circuit board to complete the mission.
The smallest possible resistance is = 6.067 ohms
The voltage across each of the resistors should be approximately 9.99 volts.
The current in each of the branches will be:
•
•
•
•
10
Ω
resistor: approximately 1.0 A
20
Ω
resistor: approximately 0.5 A
100
Ω
resistor: approximately 0.1 A
200
