What else can I help you with?
100w bulb and 60w bulb connected in parallel to 220v which will glow brightly?
Total supply voltage = 220vrated power of first lamp= 100 wattso current though it, I=p/vI=100/220=.45 ampsResistance offered by first lamp=220/.45= 488 ohms( i avoid fractions)..............................................................rated power of second lamp=60 wattsvoltage is same, so current through it = 60/220=.27 ampsresistance of second lamp = 220/.27=814 ohms( i avoid fractions).........................................................................power drawn by first lamp =I12 R=(.45)2 * 488 =98.82(=100)power drawn by second lamp =I22 R=(.27)2 * 814 =59(=60)...................................................................................SO 100 WATT BULB WILL GROW BRIGHTER AS IT HAS MORE POWER
What are the three components in a gas discharge lamp system?
A gas discharge lamp has a gas and has a cathode, an anode, and an ignition electrode. Individual discharges of a series of lamp discharges are spaced at least one millisecond from each other, and the individual discharges are generated by providing an electrical charge between the cathode and the anode and providing two or more electrical pulses to the ignition electrode. The second and following electrical pulses occur within a predetermined time of the first pulse. The electrical charge between the cathode and anode is of sufficient voltage and current to create an electrical arc between the cathode and the anode with the gas is ionized.
Which kind a light bulb uses the least amount of energy a fluorescent lamp a halogen lamp a incandescent lamp or a heating lamp?
Fluorescent lights use far less energy than any of the others listed.
Does a lamp plugged in but not on draw electrical current?
No, a lamp plugged in but switched off does not draw electrical current. The switch on the lamp has the electrical circuit in the open position. In open circuits no current will flow. As soon as you close the circuit the lamp will start using power at a rate that is the wattage of the bulb. It is this wattage that you pay your utility company to supply.
How much energy does a lamp use?
well it depends on the type of lamp but it should say on the packaging
How much electrical energy does a 100W lamp use in 1 hour?
100 Watts is 100 Joule/second. If you want the answer in Joule, you can base your calculations on that. On the other hand, the electrical company will charge you by the kWh. In this case, it is more convenient to calculate as follows: 100W = 0.1 kW, that is the same as 0.1 kWh/hour.
Does a 100w lamp use more energy than two 60w lamps?
NO. Two 60W lamps will use 120W - which is more than 100W !!
How much electrical energy is produced by a light bulb with the power ratings of 60w?
A lamp doesn't produce electrical energy; it utilises it. The power-rating of the lamp will tell you the rate at which that lamp uses expends energy at its rated voltage. For example, a 60-W lamp will expend energy at 60 joules per second.
What energy does the lamp have?
The lamp has electrical energy, which is converted to light energy when the lamp is turned on.
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 is the energy transfer for a lamp you plug into the wall?
The energy transfer for a lamp plugged into the wall involves the electrical energy from the power source (wall outlet) being converted into light energy by the lamp's bulb. The electrical energy powers the lamp's circuit, which then produces light as a form of energy.
What energy transformations occur in a lamp?
Electrical energy is transformed into electromagnetic energy.
What type of energy is a lamp plugged in and turned on to light a dark room?
it starts with electrical thats the main one but there is more
What energy is present in a lighted lamp?
The energy present in a lighted lamp is primarily electrical energy, which is converted into light and heat energy. The electrical energy is used to power the lamp's filament, which emits light and produces heat when it becomes incandescent.
What energy transformation's in a lamp?
Electrical energy is transformed into electromagnetic energy.
How does a heat lamp provide an example of energy transformation?
A heat lamp transforms electrical energy into heat and light energy. The electrical energy powers the lamp, which then converts it into heat and light, providing warmth and illumination in the surrounding area.
What energy transfers in a lamp?
In a lamp, electrical energy is transferred into light energy and thermal energy. When the lamp is turned on, the electrical energy from the power source is converted into light energy, which illuminates the surroundings. Additionally, a portion of the electrical energy is also converted into thermal energy, which is why lamps can feel warm to the touch after being on for a while.
