circuit analysis I

Question 1

Positive charge moves from positive polarity to negative polarity

Answer 1

the element absorbs energy that
appears as heat, mechanical energy, stored chemical energy, or as some other form.

Question 2

Positive charge moves from negative polarity to positive polarity

Answer 2

the element supplies energy

Question 3

Electrochemical battery - positive power

Answer 3

Battery is being charged

Question 4

Electrochemical battery - negative power

Answer 4

Battery is being discharged. the energy
supplied by the battery is delivered to some other element in the circuit.

Question 5

passive reference configuration

Answer 5

If the current reference enters the positive polarity of voltage, it’s called passive reference configuration

Configuration where reference direction of current is the same as reference direction of voltage

Question 6

ideal conductor voltage

Answer 6

The voltage between the ends of an ideal conductor is zero regardless of the
current flowing through the conductor.

Question 7

what does it mean when we say that points are shorted?

Answer 7

The voltage between the ends of an ideal conductor is zero regardless of the
current flowing through the conductor.

Question 8

ohm’s law non-passive configuration

Answer 8

v = -iR
