The electricity describes phenomena related to electric charge.
It explains electric current and voltage,
but also electrical resistance, as well as electric and magnetic fields.
Kirchhoff's laws describe the relationship
between electric current and voltage in an electrical network.
Get to know the rules here
how they help you in the comprehension of electric circuits.
Measuring Current Voltage
How do you measure current and voltage in a DC circuit?
What should you keep in mind and how do you measure resistance?
Here you find out and recognize the relationships.
Batteries are everyday objects.
They are a reliable source of electric energy
to a large variety of electric circuits.
Find out here the characteristics of batteries, how they perform in a circuit
and what practical rules result from it.
