3. Consider the following simple circuit. d) The current flowing in this circuit is constant in time. What does this imply about the speed with which the charge carriers move around the circuit? e) Recall that according to the work-kinetic energy theorem, the net work done on the charge carriers must equal the change in their kinetic energy. Considering your answer from part (d), what is the net work done on the charge carriers as they go around the circuit? a) What is the potential difference between one terminal of the battery and the other? b) Considering your answer from part (a), how much work does it take to bring an element of charge dq from the "bottom" terminal to the "top" terminal? f) We found in part (c) that the battery does positive work on the charge carriers as they move around the circuit. So something else must be doing negative work on the charges as the move around, in order to satisfy the work- kinetic energy theorem. What element in the circuit is doing negative work on the charges? c) Considering your answer from part (b), at

Three-Phase Transformers
Three-segment transformers are a type of transformer used to transform voltages of electrical systems into three ranges. Two type transformers are shell-type transformer and core type transformer. In brief, it could be described because of the exquisite kinds of configurations.
Transformer
Ever since electricity has been created, people have started using it in its entirety. We see many types of Transformers in the neighborhoods. Some are smaller in size and some are very large. They are used according to their requirements. Many of us have seen the electrical transformer but they do not know what work they are engaged in.
Question
please answer d, e and f only :)
Transcribed Image Text:3. Consider the following simple circuit.
d) The current flowing in this circuit is constant
in time. What does this imply about the speed
with which the charge carriers move around
the circuit?
e) Recall that according to the work-kinetic
energy theorem, the net work done on the
charge carriers must equal the change in their
kinetic energy. Considering your answer from
part (d), what is the net work done on the
charge carriers as they go around the circuit?
a) What is the potential difference between one
terminal of the battery and the other?
b) Considering your answer from part (a), how
much work does it take to bring an element of
charge dq from the "bottom" terminal to the
"top" terminal?
f) We found in part (c) that the battery does
positive work on the charge carriers as they
move around the circuit. So something else
must be doing negative work on the charges as
the move around, in order to satisfy the work-
kinetic energy theorem. What element in the
circuit is doing negative work on the charges?
c) Considering your answer from part (b), at
what rate is the battery doing work on the
charges in the circuit? Answer in terms of the
symbols on the diagram.
g) In order to satisfy the work-kinetic energy
theorem, what must be the rate at which heat
is lost through the resistor? Answer in terms
of the symbols on the diagram. *
