The brightness of a light bulb is directly proportional to the voltage applied to it. Increasing the voltage increases the brightness of the light bulb, while decreasing the voltage decreases the brightness.
Voltage applied (voltage at source, resistance of wire and conections etc), ground resistance, designed brightness of element in comparison to the applied voltage
If voltage varies then current varies with constant resistance.
because it does!
Changing the voltage in a circuit will alter the current flowing through it. According to Ohm's Law, the current is directly proportional to the voltage in the circuit. Increasing the voltage will lead to an increase in current, and vice versa.
Changing the temperature increases the change in energy.
in photoshop you change it via adjustments panel. just go to the window tab and click on adjustments and then the sun icon. from here you can change the brightness and contrasts.
Wire has a certain amount of resistance. As electricity flows down the wire, some of the voltage is lost in the wire before reaching the lamp. So, the longer the wire, the less voltage the lamp gets, and the dimmer it will be.
Yes, there may be a difference in bulb brightness depending on factors like the voltage applied, resistance in the circuit, and the type of bulb used. These factors can affect the current flowing through the bulb, ultimately impacting its brightness.
Voltage loss. On a long run you will loose some voltage so it is sometimes necessary to increase the wire size to compensate for the voltage loss. This loss of voltage will cause a light to be dim as it is not receiving the correct voltage that is was designed to use.
The brightness of a bulb is directly related to the amount of power it consumes. The higher the wattage of the bulb, the brighter it will be. Additionally, factors like the type of bulb (incandescent, LED, fluorescent) and the age of the bulb can also affect its brightness.
Resistance is affected by the length, cross-sectional area, and resistivity of the conductor. The resistivity, in turn, is affected by temperature. So only by changing one of these four factors will the resistance of a conductor change. Changing voltage will have no affect upon the conductor's resistance.
