Using the formula power = current × voltage, find the current drawn by a 1700-W toaster connected to 150 V .?
A) Using the formula power = current × voltage, find the current drawn by a 1700-W toaster connected to 150 V .
B) Then, using the equation current = voltage/resistance, find the resistance of the toaster.
2 AnswersPhysics1 week agoWhat is the resistance of the device (how many ohms)?
Rearrange the equation current = voltage/resistance to express resistance in terms of current and voltage. Then solve the following: A certain device in a 120-V circuit has a current rating of 30 A .

Physics2 weeks agoThey are brought close to each other without contact. What will occur?
A negatively charged metal sphere is hanging freely next to a neutral metal sphere. They are brought close to each other without contact. What will occur?
Question 3 options:
1)
The previously neutral sphere will become negatively charged, and they will repel each other.
2)
Induced charge separation will occur on the neutral sphere, and they will attract each other.
3)
Induced charge separation will occur on the neutral sphere, and they will repel each other.
4)
Particles in the neutral sphere will undergo polarization, and they will attract each other.

A negatively charged metal sphere is hanging freely next to a neutral metal sphere. They are allowed to contact each other. What will occur after contact?
Question 2 options:
1)
The previously neutral sphere will become positively charged, and they will attract each other.
2)
The previously neutral sphere will become negatively charged, and they will repel each other.
3)
Induced charge separation will occur on the neutral sphere, and they will attract each other.
4)
Nothing will happen since one of them is neutral.
