Wendy Croft 12NB Investigating the Emf and the internal resistance of a dry cell The objective of this coursework is to find the Emf of the circuit and the internal resistance of a cell. I am going to use this by measuring the resistance (ohms), current (Amps) and voltage (volts) of a circuit. The below diagram shows how I am going to set up my experiment: Apparatus: Wires Switch Dry cell Ammeter Variable Resistor Voltmeter By using the variable resistor above, I will measure eleven different readings on an Ammeter and a Voltmeter. I am able to do this as the variable resister measures resistance from 0 to 10 ohms. I will then reverse this procedure by taking the readings from the Voltmeter and the Ammeter when the resistance goes from 10 to 0 ohms. I will do this because by doing this I can view whether or not the original results were...
