When a lamp is switched off is the electrical current to the light open or closed?

Open and closed does not refer to electrical current or the flow of electricity. Open or closed refers to the state of an electrical circuit.
When a lamp is turned on electricity flows through wires, the switch and the lamp; and the circuit is considered closed. When a lamp is switched off the circuit is considered open (or broken) and the flow of electric current is stopped.

When a light switch is turned on what is done to the curcuit?
When a light switched is turned on the circuit is usually closed.
What happens when the torch is switched on?
current flows and we have light from bulb....
Why does the bathroom light spark when switched on?
You will find a loose electrical connection where the spark is occuring.
Does closed circuits work?
Closed circuits work, they have all the wires connecting from the battery, the switch and the lightbulb that is needed for the electrical current to flow through the battery through the closed switch into the light bulb and back into the battery. Therefore it works.
What does the green light on the Nintendo DSi mean?
That's just the 'on' light to show the DSi is switched on, even when the lid is closed.
Is electrical current greater before or after light bulb?
Electrical current is equal throughout a series circuit.
What is bulb and its proccess?
A light bulb is an electric light that uses the process of a filament wire that is heated to produce an electrical current. When the electrical current passing throught the light bulb it produces light.
Plug a lamp into an electrical socket and you turn electrical energy into this form of energy?
-- None at all if the lamp is switched off.-- If the lamp is switched on, then electrical energy is turned into a little bit ofvisible light energy and a comparatively larger quantity of heat energy.
What causes electrical energy to be transformed into heat and light energy as a current flows in a light bulb?
Eletric current
What is the difference between heavy and light current in electrical engineering?
light current deals with control and telecommunication.while heavy current deal with machine which consume high current such as transformer ,generator ,electrical distribution above 415 volts
Why do light filament bulbs usually blow when they are first switched on?
because when they are first switched on a large surge of electrical current flow through a cold filament. When you first switch on the bulb the resistance is small, so you get a current surge which breaks the weakened filament. The filament is weakened by repeated heating and cooling from the bulb being turned on and off; which makes it brittle.
What do you mean by open and closed electric circuit?
An open circuit is one where the current is not able to complete the circuit. An example could be a light bulb connected to power but switched off, the circuit being broken by the switch, and considered "open." When flipping the switch On, it connects the power and the circuit is then closed.
