The current is 0.4 A and the bulb in the circuit is bright. What will happen to the brightness of the bulb if you put another bulb in series in the circuit?

ANSWER: The brightness of both bulbs will decrease. If the bulbs are identical the current will decrease to 0.2 Amps. This is a simple series resistive circuit, the more bulbs you add in series both the amperage and bulb brightness will continue to go down.

Does a large current in a circuit make a bulb bright or dim?
The glow of the bulb is due to heating of the filament to the incandescent level. Joule's heating effect gives the formula H = I2 R t. Hence more the current then more the heat and so more brightness. Thus large current makes the bulb brighter no doubt. At the same time if current exceeds the nominal level then filament would get melted and get fused.

When you add a second battery to a series circuit what happens?
Adding a seound battery to a series circuit will increase the voltage, and require less current to keep the lights (if there are any on) as bright. Say you have a 6v battery, then you add another 6v battery. the voltage of the circuit would be 12v
