How to produce an electric current?

I f you take a magnet and move it in to a coil of wire the voltage has been induced to a smaller voltage to induce it to a bigger voltage you move the magnet out of the coil in the opposite direction. In a generator, a magnet rotates inside a coil of wire. This includes a current if the coil is connected to a complete circuit. Otherwise it will induce the voltage and not the current. Things you can use to create a greater current is to use

  • A stronger magnet.
  • Create more turns on the coil of wire.
  • Increase the area of the coil.

How to make a current flow?

To make a lamp light you must send an electric current through it. You can do this by putting a voltage across its ends. Also you must use 2 wires and attach them to both ends of the component you are using and also to a battery or batteries and then to the switch. This is just one of the examples but there are many more ways of making a current flow. After that you press the switch and the current shall run through the switch.

How to measure a voltage?

To measure a voltage you have to use a voltmeter. When measuring the voltage you must connect the voltmeter across the lamp because this is what pushes the current through the lamp. To set it up you must have four wires connect one between the lamp and the voltmeter and another one on the other side then connect one on the top end of the battery and another one on the other end of the battery.
