A student is comparing a step-up transformer with a step-down transformer. Which data should she collect from each device?
the ratio of incoming and outgoing currents
the ratio of incoming and outgoing voltages
the ratio of the number of turns in the primary coils
the ratio of the number of turns in the secondary coils
Answer: The ratio of incoming and outgoing voltages.
After doing a bit of Research it seemed like the main difference between the two transformers :)
1. The induced current will increase.
2. A power source such as a battery.
3. The creation of an electric current or magnetic field depends on the movement of electrons.
4. The ammeter will detect an increase in current, and the compass will detect a stronger magnetic field.
5. Without a closed circuit, electrons cannot flow from one point to another.
6. An ammeter
7. the ratio of incoming and outgoing voltages
8. 13
9. It’s a step-up transformer because the secondary voltage is greater than the primary voltage.
10. In a motor, an electric current creates a magnetic field.
11. Voltage and electric current are induced.
12. Move the magnet through loops of wire
^^ 100% on the Electricity and Magnetism Unit Test! if these are not the answers on the test, they changed them!
Stay safe out there and good night.
Shelly is surprisingly correct
yup all correct thank u :)
Oh, student! When it comes to comparing transformers, here's what you should collect:
For both step-up and step-down transformers, you'll want to measure the ratio of incoming and outgoing voltages. That's the volts, baby!
And to top it off, you should also gather data on the ratio of the number of turns in both the primary and secondary coils. Count those turns, my friend!
So remember, it's all about volts and turns. Get those numbers, and you'll be transformer-savvy in no time!
To compare a step-up transformer with a step-down transformer, the student should collect the following data from each device:
1. Ratio of incoming and outgoing currents: Measure the primary current (incoming current) and the secondary current (outgoing current) of both the step-up and step-down transformers. The student should compare the ratios of these currents to see how they differ between the two transformers.
2. Ratio of incoming and outgoing voltages: Measure the primary voltage (incoming voltage) and the secondary voltage (outgoing voltage) of both the step-up and step-down transformers. The student should compare the ratios of these voltages to determine how they differ between the two transformers.
3. Ratio of the number of turns in the primary coils: Count the number of turns in the primary coil of both the step-up and step-down transformers. Compare the ratios of these numbers to see if there is any difference between the two transformers.
4. Ratio of the number of turns in the secondary coils: Count the number of turns in the secondary coil of both the step-up and step-down transformers. Compare the ratios of these numbers to determine any variation between the two transformers.
By collecting and analyzing these data, the student will be able to understand how the step-up transformer and step-down transformer differ in terms of current ratios, voltage ratios, and the number of turns in their primary and secondary coils.
