WebThe voltage output of a device is measured across its terminals and, thus, is called its terminal voltage V. Terminal voltage is given by V = emf − Ir, where r is the internal resistance and I is the current flowing at the time of the measurement. I is positive if current flows away from the positive terminal, as shown in Figure 2. WebThe potatoes act as independent batteries, providing induced EMF as they are connected in series. The reason they act as a battery is because the copper and zinc electrode …
WebE = electromotive force (V) I = current (A) R = resistance of the load in the circuit (Ω) r = internal resistance of the cell (Ω) This can be simplified into the form: E = IR + Ir = V + Ir. … Web1. Assemble your cell. Use the copper and zinc sheets as electrodes, inserting one in each end of the potato. Use crocodile clips to make connections to the circuit. 2. Set up a circuit to measure the pd across the cell and the current drawn from the cell, initially with 4.7 k as a load for the cell. 3. Alter the load resistance.
