The figure shows a resistor of resistance R = 6.27 Ω connected to an ideal battery of emf  = 13.9 V by means of two copper wires. Each wire has length 21.9 cm and radius 2.90 mm. In dealing with such circuits in this chapter, we generally neglect the potential differences along the wires and the transfer of energy to thermal energy in them. Check the validity of this neglect for the circuit of the figure below. What is the potential...

7) A circuit consists of a capacitor (capacitance of 1μF) and a resistor (resistance 1000 Ω) in series, with a battery supplying a potential difference of 12.0 V. At time t=0 a switch is closed to allow current to flow in the circuit for the first time. Remember that the potential difference supplied by the battery ε is not the same as the potential across the capacitor ΔV unless a lot of time has elapsed. Also an RC circuit is...

The internal resistance of a battery is relatively small when the battery is new but increases as the battery ages. When a new 12.0-VV battery is attached to a 100 ΩΩ load, the potential difference across the load is 11.9 VV. After the circuit has operated for a while, the potential difference across the load is 10.9 VV . Part A By how much has the internal resistance of the battery changed? Express your answer using two significant digits.
