The diagram shows the direction of flow of current and the labeling - A, B, C, D, E and F
The function of each part is as follows:
A- A is the Ammeter, which measure the flow of current in the circuit
B- Cell: acts as a source of direct current for the circuit
C- key: Key puts the current, on and off in the circuit
D - Load: load is an appliance connected in a circuit which can be a combination of different electrical components or a resistance (bulb).
E - Voltmeter: It measures the potential difference between two points of a circuit.
F - Rheostat: it controls the flow of control in a circuit
