C) Ammeter is measuring the total current of the circuit and current in the series is the same.
Hence, find the current of Reff by using Ohm's Law as Voltage is given n resistance was found in part (a)
D) current was found in part (c), using ohm's law p.d is able to find.
E) Voltage of the dry cell = total voltage which means the sum of voltage drop across 1 ohm + Voltage across Voltmeter
