When applying Kirchoff’s rules, when is the change in potential across a resistor negative?
a) When the resistor is connected to the positive side of an emf.
b) When the resistor is connected to the negative side of an emf.
c) When the resistor is traversed in the same direction as the current.
d) When the resistor is traversed in the opposite direction of the current.
e) None of the above.
What is the ’junction rule’?
a) One of Kirchhoff’s rules that involves potential differences
b) A rule that can’t be used for circuits with capacitors
c) One of Kirchhoff’s rules that involves currents
d) A rule that is used in addition to Kirchhoff’s rules for
circuits containing junctions of wire
e) None of the above.
What is the ’loop rule’?
a) One of Kirchhoff’s rules that involves currents
b) A rule that can’t be used for circuits with capacitors
c) A rule that is used in addition to Kirchhoff’s rules for circuits containing loops of wire d) One of Kirchhoff’s rules that involves potential differences
e) None of the above.
Why is the terminal voltage lower than the emf voltage when a current run through the emf?
a) Actually, the terminal voltage is always lower than the emf voltage.
b) Because there is a current through the load resistor.
c) Because there is a voltage drop across the internal resistor.
d) Because load resistor produces a back emf.
e) None of the above
