Construct a simple series circuit with one resistor. Use the circuit building interactive linked on the Dry Lab page of this activity to answer question 24. 24. Use the voltmeter and ammeter to determine the voltage and current of the circuit. Open the switch, and again measure the voltage and current of the circuit. What happened to the voltage and current after the switch was opened

First answer marked as brainiest which is the correct equation describing the first law of thermodynamics? a) when the internal energy of a system changes, it equals the amount of heat added plus the work done. b) when work is done by the piston, it is equal to the heat added plus the change in internal energy of the system. c) when heat is added to the system, it is equal to the amount of work done by the piston plus the change in internal energy of the system.
