Construct a circuit with resistors (or light bulbs) in series and record current and voltage. How does the current through the resistor (or the bulb) in a single-resistor circuit compare with the current through the same resistor when it is connected in series with a second resistor? Now construct a circuit with resistors (or light bulbs) in parallel and record current and voltage. Compare the current through the battery in the series circuit with the current through the battery in the parallel circuit. Is it lower, the same, or higher?

Expert Solution
Step 1
Part A
When resistors are connected in series connection, they will share the voltage provided by the battery but the flow of current will be the same at every point of the circuit.
This value of current will decrease if the equivalent resistance of the resistor combination increases
Since the bright of the bulb is dependent on the flow of current and current is inversely proportional to the equivalent resistance, adding more bulb in series will reduce the brightness of the bulb.
