That will depend on whether they are added in series or parallel.
To make a simple series circuit to light a bulb, the simplest components are a power source (such as a battery); a switch (to turn the power on or off); the bulb (obviously !); and some wires to connect everything together.
You need a Battery, Light Bulb, Ammeter, Switch.
Yes, two batteries will make a light bulb brighter than one, provided that the batteries are placed in series. The brightness of the bulb is determined by the voltage, and placing two batteries in series rather than just using one increases the voltage.
If you add another battery in series with the first one, then the bulb willglow brighter, and may burn out if you carry things too far.If you add another battery in parallel with the first one, then the brightnessof the bulb won't change, but the battery will last twice as long.
you can make a torch bulb
You need a Battery, Light Bulb, Ammeter, Switch.
If you add resistance to the circuit the bulb will shine with a fainter light ... the higher the resistance is the fainter it will shine
Make a circuit with 2 wires a batery and a light bulb and touch wire to medle on light bulb
circuit
you can make the light bulb turn on. Ooh ooh i know. it's a circuit!
Before constructing a simple circuit we must first have in mind which type of source is to be supplied to the circuit . A simple circuit may consist of the following components such as capacitors, resistors , inductors etc
To make sure that the batteries come into contact with the plate that holds the bulb.
