When the supply voltage to a series motor is reduced, the speed of the motor will also decrease. This is because a series motor's speed is directly related to the applied voltage; as the voltage drops, the current through the motor reduces, leading to a decrease in both torque and speed. Additionally, the reduced voltage results in a lower magnetic field strength, which further contributes to the decrease in speed. Thus, the motor will operate at a lower speed under reduced voltage conditions.
If a rheostat is connected in parallel with a light bulb, the setting of the rheostat should have no effect on the performance of the light bulb, as long as the power supply is able to maintain its output voltage and deliver the current demanded by their parallel combination.
In a combination circuit, which includes both series and parallel components, the total supply voltage is distributed among the components. In series sections, the voltage is divided based on the resistance of each component, while in parallel sections, the voltage across each branch remains equal to the supply voltage. The total supply voltage remains constant throughout the circuit, but the voltage across individual components can vary depending on their configuration and resistance.
When two additional bulbs are added in series to an existing circuit, the total resistance increases. This causes a reduction in the overall current flowing through the circuit, which results in all the bulbs receiving less voltage. Consequently, the brightness of all the bulbs will decrease as they share the reduced voltage. If the power supply cannot handle the increased load, it may also lead to dimming or flickering.
Adding additional lamps has no effect on the supply voltage supplied to you home. If the lamps are connected in series, then the sum of voltage-drops appearing across each lamp will equal the supply voltage. If the lamps are connected in parallel, then the voltage across each lamp will equal the supply voltage.
The circuit voltage or the resistance of the individual bulb is needed to answer this question. Divide the total power (400 W) by the supply voltage.

In a series circuit the total voltage is the sum of the voltage drops across all the component in series. When the voltage drops across each the individual components are added up, they will equal the supply (or applied) voltage.

Yes it can be transformed from one voltage to the other.
The rf output voltage should be proportional to the signal voltage in AM. A change in the DC supply voltage should also cause a proportional change to the rf output voltage.
By using a voltage divider, that is two resistors of the same value in series across the DC supply. Half of the supply voltage will be at the point where the two resistors is connected. But how much wattage of those resistors is also an issue.

Divide the number of lamps into the value of the supply voltage, and that will tell you the voltage drop appearing across each lamp. Bear in mind that if one of the lamps should be removed, the full supply voltage will then appear across the empty lamp holder.
The voltage across R1 would be 50 volts. This is because the voltage divider rule states that the voltage across each resistor in a series circuit is proportional to its resistance relative to the total resistance in the circuit. In this case, since both resistors are the same (20K), the voltage across each resistor will be half of the total supply voltage.
