(b) A capacitor is charged using a battery. It is then discharged through a resistor. An analogue voltmeter is used to measure the voltage across the discharging capacitor at 10 second intervals as shown below. Time t (seconds) Voltage (V) (i) 10 20 30 40 50 60 70 80 90 100 7.52 7.06 6.63 6.23 5.85 5.50 5.17 4.85 4.56 4.28 I Given that the voltage across the discharging capacitor is given by V = Ve== show that by taking logs, this equation can be written in the linear form given by y = mx + c. State the gradient and y - intercept in algebraic terms.
