Chapter 5 Study Guide: Electric-Circuit Interactions Electric-circuit interaction : source of electrical energy is connected in a closed path of conductors to an energy receiver Conductors : materials that can be included in a circuit to light bulb Insulators : materials that do not allow bulb to light when included in circuit Parallel circuit : multi-loop Series circuit : single loop Electric-Circuits and Energy Electrical energy is transferred from battery to bulb, causing it to light Decrease in chemical potential energy inside batter and increase in thermal energy inside bulb Battery dies when there is no more chemical potential energy For many systems that warm up, temperature reaches certain maximum value (operating temperature) - Past this, increase in thermal energy results from electrical energy being transferred is balanced by decrease in thermal energy resulting when heat energy is transferred out - When balance is reached, thermal energy no longer changes and temperature of system remains constant EQUILIBRIUM STATE

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
