NEW QUESTION # 33
___________ measures the amount of electrical current flowing through a circuit during a specific time interval.
- A. Watts
- B. Ohm
- C. Ampere
- D. Volts
Answer: C
Explanation:
Explanation
An ampere (A) is the unit of measurement for electric current. It measures the amount of electrical current flowing through a circuit during a specific time interval. The ampere is named after Andre-Marie Ampere, a French mathematician and physicist who was one of the main discoverers of electromagnetism.
Ohm () is the unit of measurement for electric resistance, which is the opposition to the flow of an electric current through a circuit.
Volt (V) is the unit of measurement for electric potential difference, which is the energy required per unit charge to move a test charge between two places in a static electric field.
Watt (W) is the unit of measurement for power, which is the rate at which energy is used or generated in an electrical circuit.

NEW QUESTION # 35
AC is more easily distributed than DC. This is because:
- A. AC can be transformed from a low voltage to a high voltage and back again with a transformer. DC cannot.
- B. AC can be transmitted using lighter wires.
- C. Wires have less resistance if they are carrying AC
- D. DC needs wires to be totally insulated, while AC wires can be bare, hung from insulator on pylons.
Answer: A
Explanation:
Explanation
AC can be transformed from a low voltage to a high voltage and back again with a transformer, while DC cannot. This makes it easier to distribute AC electricity over long distances and is why it is used more widely than DC electricity. A and B are also true, as wires carrying AC can be bare and don't need to be totally insulated. Wires have less resistance when carrying AC electricity, which is why it is more efficient than DC.
