Question 5:

Medium

A group of students is conducting a science project on electricity and they are building an electrical circuit with three resistors in series. The first resistor has 4Ω, the second has 6Ω, and the third has 2Ω. They connect these three resistors to a 12V battery and are curious about how the current and voltage are distributed in the circuit. Considering this situation: a) Calculate the total resistance of the circuit. b) Determine the total current in the circuit. c) Identify the voltage across each resistor and share your observations on the work done by the resistors regarding sustainability and energy efficiency.
