What switches must be closed in order for the light bulb to light up?
To light up the bulb, the two-way switch must be closed in the on position at both the 'Switch 1' location and the 'Switch 2' location. This will complete the circuit and allow electricity to flow to the light bulb, turning it on.
When the switch is closed how will the energy convert into light and heat by bulb compare with the energy converted into light and heat by bulb?
When the switch is closed, the electrical energy from the power source will flow through the circuit and into the light bulb. The bulb's filament will get hot due to the resistance, producing light and heat. The efficiency of energy conversion into light and heat by the bulb depends on the bulb's design and materials, as well as any losses due to inefficiencies in the circuit.
What must be true for a circuit to light a bulb?
For a circuit to light a bulb, there must be a closed loop for the flow of electricity. This loop typically consists of a power source (e.g. battery), wires, a switch, and the bulb. When the switch is closed, the circuit is complete and electricity can flow through the wires to the bulb, causing it to light up.
Three different bulbs are connected in series when switch is closed the last bulb does not glow why?
When bulbs are connected in a series circuit, each bulb depends on the voltage from the previous bulb to light up. If the last bulb doesn't glow, it may indicate that there is a break in the circuit somewhere before that bulb, such as a loose connection or a blown fuse. This interruption in the circuit would prevent the flow of electricity to the last bulb, causing it not to light up.
What energy conversions occur when the switch is closed?
When the switch is closed in an electric circuit, electrical energy from the source is converted into other forms of energy. For example, the electrical energy is converted into light and heat in a light bulb, or into mechanical energy in a motor.
When the switch is closed which light bulb will light light bulb 1 2 or 3?
It depend on where the switch is located in the circuit.

Why will a bulb not light if a switch is open in a circuit?
It will not work because it has to be closed so the electricity can go to the bulb.
When the switch is closed why does the bulb light up?
When the switch is closed, it completes the electrical circuit, allowing current to flow from the power source to the bulb. This flow of current energizes the filament or LED inside the bulb, causing it to emit light. The closed circuit enables the necessary voltage and current to reach the bulb, resulting in illumination.

What circuits are closed paths that will allow electricity to travel in a loop and make a light bulb work?
a switch
What is in a light bulb when it's switch is turned on or connected the electricity flows through what we call?
A closed current
Is a light bulb a closed system?
The light bulb is a closed system: no mass transfer.
What seems to be making the light bulb turn on in your circuit?
The light bulb in the circuit turns on due to the flow of electric current, which is facilitated by a closed circuit. When the switch is closed, it completes the circuit, allowing electrons to move from the power source through the bulb, causing it to emit light. The resistance in the bulb converts electrical energy into light and heat, resulting in illumination.
How does a light bulb dimmer switch work to adjust the brightness of a light bulb?
A light bulb dimmer switch works by controlling the amount of electricity flowing to the light bulb. By adjusting the voltage, the dimmer switch can regulate the brightness of the light bulb.
Why does an open light switch turn off the light?
An open light switch interrupts the flow of electricity in the circuit. When the switch is in the "off" position, it creates a gap that prevents electrical current from reaching the light bulb. Without the current, the bulb cannot produce light, effectively turning it off. Conversely, when the switch is closed, the circuit is complete, allowing current to flow and the light to turn on.
