Question

Choose the BEST answer to the following:

As more lamps are connected to a series circuit, the current in the power source

(a) increases.

(b) decreases.

(d) None of these.

Expert Solution

Step 1

As the more lamps are connected in a series circuit the brightness of each lamp diminishes.

Since the more the lamps in the circuit more the resistance, more the resistance less the current in the circuit and the source.
