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...
