What happens to the brightness of the bulbs in a parallel circuit?
A lamp's rated power only applies when the lamp is supplied with its rated voltage. If you connect the lamps in series, with the same supply voltage, then the lamps are no longer subjected to their rated voltage and, so, will not operate at their rated power.
What is the total voltage of a battery containing five 2 V cells connected in series?
Total voltage output of 5 2v cells connected in series would be 10v
How are resistor connected in series?
when we want maximum resistance they are connected in series. when resistors are connected in series total resistance is maximum when resistors are connected in parallel total resistance is minimum for series total R=R1+R2+R3......... for parallel R1 in parallel to R2 total 1/R=(1/R1)+(1/R2) ie R=(R1*R2)/(R1+R2)
When is it usually desirable to connect cells in series?
In electronics circuits current is common in series circuits and voltage is common across parallel circuits. LEDs in series draw less current, but require more voltage. Total power remains the same until multiple drivers are introduced in a parallel configuration.
What would the current draw be if there was six ten ohm resistors connected in series across a 120 volts?
The total current in a circuit consisting of six operating 100 watt lamps connected in parallel to a 120 volt source is 5 amperes. Since power is volts times amps, take 600 watts (100 times 6) and divide by 120 volts to get 5 amps.
What happens to the power output of the source if more lamps are connected in parallel?
Nothing will happen to the possible output power of the power source i.e it will not increase. Each power source has its maximum possible output power. Adding more lamps in parallel will result in a drop in the circuit's total resistance which causes the total current drawn by the lamps to increase. Your wires might be burnt as a result so be careful.
When two light bulbs are connected in series the?
When two light bulbs are connected in series , there is voltage drop which causes the second lamp to dimAnswerWhen two lamps are connected in series, neither lamp will be subject to its rated voltage and, so, each lamp will be dim. Surprisingly, perhaps, the lamp with the higher power will be dimmer than the lamp with the lower power!
If one of three lamps blows out when connected in parallel what happens to the current in the other two?
If three lamps are connected in parallel and one blows out, the current in the other two does not change. This assumes that the net change in total current does not cause the power source to change voltage.
What happens to the brightness of the bulbs in a parallel circuit?
A lamp's rated power only applies when the lamp is supplied with its rated voltage. If you connect the lamps in series, with the same supply voltage, then the lamps are no longer subjected to their rated voltage and, so, will not operate at their rated power.
Why does the glow of two lamps decrease when they are connected in series?
Because the total current is divided between the two components. For example, if the current was one amp, and you connected two bulbs in series, ech bulb would get half an amp of current. As brightness is proportional to current, this means they glow more dimly.
What is the total voltage in a series circuit when multiple resistors are connected in series?
In a series circuit with multiple resistors connected in series, the total voltage is equal to the sum of the individual voltages across each resistor.
How can you measure the ampere or watt for power supply?
You can measure the current and power of a 'power supply', using an ammeter and a wattmeter. With the power supply connected to its load, the ammeter must be connected in series with the power supply's input. The wattmeter's current coil must also be connected in series with the power supply's input, and its voltage coil must be connected in parallel with the supply, taking the instrument's polarity markings into account.
What is the total voltage of a battery containing five 2 V cells connected in series?
Total voltage output of 5 2v cells connected in series would be 10v
How do you calculate the total mA needed to power 3 9v DC 200 mA devices?
Separate devices should always be hooked up in parallel, and not series. Therefore, you would combine the total current requirement, which in this case is 600mA or 0.6A. You would therefore need a 9V power supply that is capable supplying at least 0.6A. It depends on whether the devices are connected in series or parallel or some combination of the two. The current in a series circuit is the same throughout the circuit. The current in a parallel circuit is the sum of the current in each parallel branch If the three devices are connected in series, the required current is 200mA. If the three devices are connected in parallel, the required current is 600mA The total power required by a circuit is the sum of the power consumed by each component. It doesn't matter if the devices are connected in series or parallel. Power = voltage x current. If the three devices are in series, the power consumed by one of them is 9 x .2 = 1.8 watts. The total power consumed is 1.8 x 3 = 5.4W If the three devices are connected in parallel, the power consumed is 9 x .6 = 5.4W Notice that the power consumed is the same for the series and parallel combination. The battery (or power supply) must be able to supply 5.4 watts.
What happens to the power outputs of the sources if more lamps are connect in parallel?
Nothing will happen to the possible output power of the power source i.e it will not increase. Each power source has its maximum possible output power. Adding more lamps in parallel will result in a drop in the circuit's total resistance which causes the total current drawn by the lamps to increase. Your wires might be burnt as a result so be careful.

What is the total inductance of two inductors connected in series?
Inductance in series is the sum of the individual inductances.
