Electricity and Magnetism

Question 1

What will the other Ammeters in a series circuit read if one reads ‘5A’?

Answer 1

5A - the current is the same everywhere is a series circuit

Question 2

What is the symbol for a voltmeter?

Answer 2

A ‘V’ enclosed in a circle, connected with two lines to the circuit

Question 3

What is the difference between a battery and a cell?

Answer 3

A battery is two cell symbols connected by a dotted line, each facing the same way. The way they face tell us which way the current is moving.

Question 4

Define voltage

Answer 4

Voltage describes the “pressure” that pushes electricity. The amount of voltage is indicated by a unit known as the volt (V), and higher voltages cause more electricity to flow to an electronic device.

Question 5

Define current

Answer 5

The flow of electrons, measured in amps

Question 6

Define magnetic field

Answer 6

The area of magnetic force around a magnet

Question 7

What is magnetism?

Answer 7

The force of attraction or repulsion of magnetic materials
