Electrical Circuit Analysis: Three Lamps Connected in Parallel

How are the three lamps connected in the circuit?

The lamps' constant voltage indicates they are connected in parallel in the circuit. Each branch of this setup contains a lamp and the current, potential difference, and resistance values in each branch comply with Ohm's Law, confirming this is a parallel connection.

Can you describe a suitable circuit diagram for this configuration?

Using standard circuit symbols, draw a circuit showing how the lamps and battery are connected. The battery and the three lamps are connected in parallel if they exhibit the same potential difference (voltage).

Answer:

The battery and the three lamps are connected in parallel. Each lamp maintains its listed current, voltage, and resistance, even if the other lamps were switched off.

To illustrate this, begin by drawing a line indicating the positive terminal of the battery. Another line at the bottom represents the negative terminal. Connect three branches to these lines; one for each lamp, representing parallel connections. Depict a lamp on each branch using standard circuit symbols and label them according to the data provided: Lamp 1, Lamp 2, and Lamp 3.

The values of current, potential difference, and resistance mentioned in the data table verify that this is indeed a parallel circuit connection, as they follow the rule V=IR (Ohm's Law). In this configuration, the lamps will operate independently with the same potential difference across them.
