There is no particular reason why a motor should have a bigger resistance than a bulb.

A motor's resistance must depend on what current it draws at the particular voltage it was designed to run on.

Equally, a bulb's resistance must depend on what current it draws at the particular voltage it was designed to run on.

A particular motor may have a higher resistance than one kind of bulb but that same motor may have a lower resistance than another kind of bulb.

What happens when you put an electric motor with higher resistance and a light bulb with less resistance in a series circuit. does the bulb light up and motor spin. or only the motor spin?

(Another possibility is: Bulb lights up and motor does not spin.)The result all depends on the relative resistance of the bulb and the motor, becausethat determines how much of the supply voltage appears across the light bulb, andhow much across the motor.That's one of the big problems with a series circuit: The performance of one devicedepends on the characteristics of the other devices in the same circuit. If you turnthe light off, the motor can't run at all. If the load on the motor changes, then thelight bulb flickers. And if you change the light bulb and put in one with a differentresistance, then the strength of the motor changes.


Do bigger parachutes have more air resistance or drag force than smaller parachute?

Bigger parachutes have more air resistance and drag force than smaller parachutes. This is because the larger surface area of the bigger parachute creates more friction with the air, resulting in increased resistance and drag.


Which has a higher resistance 50W lamp bulb or a 25W lamp bulb and how many times?

R1=v square/50 R2 = v square/25 = v square/25 multiplied by 2/2 = 2v square/50 R2 = 2 multiplied by R1 R2 is twice more than R1


Out of the two bulbs in the house one glows brighter than the other which one of the two has a larger resistance?

The bulb that glows brighter has a smaller resistance. This is because a larger current flows through the bulb with smaller resistance, resulting in it glowing brighter.


How does the electrical resistance of an object change - If a light bulb has X ohms of resistance three of those light bulbs in the same circuit in series have less resistance?

The resistance of a light bulb is inversely proportional to its temperature, i.e. a cold bulb has less resistance than a hot bulb. As a result, if you connect three bulbs in series to the same voltage used for one, they will each receive one third of the original voltage, causing them to use less power, causing them to generate less heat, causing them to have less resistance. If you measure the current in the circuit, there will be slightly more than one third of the original current. Given the same voltage, that means that each bulb has less resistance than originally measured, as expected. This characteristic of light bulbs is why they tend to blow out at turn-on. The starting current and power is higher than in the steady state case. You can make a bulb last much longer if you provide a soft start circuit that ramps up the voltage over a short period of time.

Which 12 volt bulb will draw the most current when connected to a 12 volt battery?

The bulb with the lowest resistance. Current = Volts / Resistance

Why armature resistance is less than 1 Ohm?

why armature resistance is very low as compare to field resistance in dc motor


Why motor has large winding in shunt resistance than armature resistance?

A motor with large windings will have greater shunt resistance than armature resistance due to the sheer amount of copper wire it must travel through. The gauge of the wire also plays a part in this process.


Does an electric motor have different resistance than an electric heater?

Yes it would be unlikely an electric motor coincidentally exactly matched the resistance of an electric heater.


Suppose in a circuit with 2 bulbs the resistance of bulb 1 is greater than that of bulb 2. how will the voltage across the two bulbs compare?

if the resistance of bulb A is 2x that of B then there will be twice as much voltage across it (ratio 2:1 ). both voltages shall equal the system voltage assuming they are in series and there are no other components in the circuit if the bulbs are in parallel the voltage across them will be equal and that of the system


What is different about the new bulb if you changed a bulb and the current decreased?

The new bulb has higher resistance than the old one did, and it's designed to use less electrical energy than the old one used.

What are the resistance values on a 10 horsepower 480 volt 3 phase motor phase to ground?

The resistance depends on how big the motor is. A small motor (less then 2-3 kW) , have greater resistance than a bigger one. Typically small motors have from 10 - 20 ohms to a few ohm. A 13 kWatt motor have typically 1-2 Ohm. A big 400 KWatt's motor have typically 10 milli ohms between the phases.


If you change a bulb in a circuit and the current decreases what is different about the new bulb?

The resistance of the new bulb is likely higher than the previous bulb. Increasing resistance in a series circuit decreases current flow. When resistance increases, less current can flow through the circuit, resulting in a decrease in current.


Out of the two bulbs in the house one glows brighter than the other which one of the two has a larger resistance?

The bulb that glows brighter has a smaller resistance. This is because a larger current flows through the bulb with smaller resistance, resulting in it glowing brighter.
