TīmeklisWhen the bulbs are connected to a voltage source, the voltage is divided over the two bulbs in series, and the power consumed by each will be U²/4R. The bulbs in parallel each have a voltage of U over them, and therefor each consumes U²/R power. In this case the claim in the question is correct. the bulbs in parallel are brightest.

Prior art keywords output lamps time delay circuit lamp Prior art date 1983-03-09 Legal status (The legal status is an assumption and is not a legal conclusion. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) Expired Lets assume that the lamp is rated at 6v, 24W and is fully “ON”, the standard MOSFET has a channel on-resistance ( RDS(on)) value … Skatīt vairāk Here the operating conditions of the transistor are zero input gate voltage ( VIN ), zero drain current ID and output voltage VDS = VDD. … Skatīt vairāk Because of the extremely high input or gate resistance that the MOSFET has, its very fast switching speeds and the ease at which they can be driven makes them ideal to interface with op-amps or standard logic gates. … Skatīt vairāk In the saturation or linear region, the transistor will be biased so that the maximum amount of gate voltage is applied to the device which results in the channel … Skatīt vairāk Thus far we have looked at the N-channel MOSFET as a switch were the MOSFET is placed between the load and the ground. This also allows for the MOSFET’s gate drive or switching signal to be referenced to ground (low … Skatīt vairāk ata kemal muhammed uzan
