1

The electrical potential difference between two points is called:

60% Answer Correctly

resistance

conductance

voltage

current
Solution

Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.

2

The sum of the voltage drops across each resistor in a __________ circuit will equal the total voltage applied to the circuit.

54% Answer Correctly

closed

parallel

series-parallel

series
Solution

A series circuit has only one path for current to flow. In a series circuit, current (I) is the same throughout the circuit and is equal to the total voltage (V) applied to the circuit divided by the total resistance (R) of the loads in the circuit. The sum of the voltage drops across each resistor in the circuit will equal the total voltage applied to the circuit.

3

This circuit diagram represents a(n):

69% Answer Correctly

parallel circuit

open circuit

series-parallel circuit

series circuit
Solution

A series circuit has only one path for current to flow. In a series circuit, current (I) is the same throughout the circuit and is equal to the total voltage (V) applied to the circuit divided by the total resistance (R) of the loads in the circuit. The sum of the voltage drops across each resistor in the circuit will equal the total voltage applied to the circuit.

4

What type of current flows in only one direction in a circuit?

82% Answer Correctly

alternating

series

direct

parallel
Solution

Direct current flows in only one direction in a circuit, from the negative terminal of the voltage source to the positive. A common source of direct current (DC) is a battery.

5

Electrons will flow as current from areas of __________ potential (concentration of electrons) to areas of __________ potential.

74% Answer Correctly

low, high

high, high

low, low

high, low
Solution

Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.
