Answer 3

Moving charge that flows through a medium

Question 4

Resistor

Answer 4

A device that opposes the flow of electric current.

Question 5

Conventional current

Answer 5

A flow of charge in a circuit from the positive to the negative terminal of a battery.

Question 6

Series circuit

Answer 6

An arrangement of cells, wires and resistors, where the resistors are connected to for only one path for current to flow.

Question 7

Parallel circuit

Answer 7

An arrangement of cells, wires and resistors, where the resistors are connected to form multiple paths for current to flow.

Question 8

Current

Answer 8

The rate of flow of charge

Question 9

Voltage

Answer 9

The work done per unit positive charge moving between two points.

Question 10

Resistance

Answer 10

A material’s opposition to the flow of electric current, and is the ration of voltage to current.
