A parallel circuit is constructed with three different branches. An ammeter is placed in each of the branches to measure the branch currents. An ammeter is also placed outside the circuit to measure the current in the voltage source.
If I1 = 2.8 A, I2 = 4.1 A, and I3 = 4.8 A, then what is the current in the battery (I_battery)?

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
