12. How does the voltage supplied to the resistor compare with the voltage supplied by the
battery in the following diagram?
А.
The voltage across the resistor is greater than the voltage of the battery.
| The voltage across the resistor is less than the voltage across the battery but
greater than zero.
C. O The voltage across the resistor is zero.
B.
13. Household circuits are wired in parallel. Adding more appliances to a parallel circuit
A. O increases the voltage sent to each appliance
В.
decrease the current sent to each appliance
C. O increases the current drawn from the circuit but does not change the current to each
appliance.
14. Two identical coils of wire are placed on a single horizontal wooden broom handle. The coils
are separated by a few centimeters. We now run identical currents in the same direction
through each coil. The coils experience:
] no forces because the currents are identical
Ja repulsive magnetic force
C.O an attractive magnetic force
А.
В.
15. An ideal transformer is used to either increase or decrease the voltage in an AC circuit. When
the output voltage is greater than the input voltage of a transformer then
A. O the power output depends on the ratio of turns in the primary and secondary
the power output is the same as the power input
В.
С.
the power output is larger than the power input
D.
the power output is smaller than the power output
