7. (1) The current in a circuit with a discharging capacitor drops exponentially: I(tz ) = 1(t)e-(tz-t1)/RC where R is the total resistance of the circuit, C is the capacitance of the capacitor, and / is the current measured at a certain time t. Choose two current measurements from the table above (preferably with a larger time interval) to estimate the resistance R of the circuit
