In this video Paul Andersen explains how resistors and capacitors affect circuits. The resistance of a resistor is affected by the resistivity of the material and the geometry of the resistor. The current through a resistor can be...

In this video Paul Andersen explains how Kirchoff's Loop Rule can be used to calculate the voltage of different components of a circuit. The sum voltage throughout an entire loop will sum to zero following the law of conservation of...

In this video Paul Andersen explains how electric circuits contain different elements which can be connected in series or in parallel. The following four elements are explained in detail; emf, resistor, capacitor, and switch. The...

New ReviewIn this video, we build directly on electric potential energy and electric potential to develop a clear, conceptual understanding of electric potential difference. Using parallel plates and a uniform electric field, you will see where...

Electric potential can feel abstract, but it doesn’t have to be! In this Flipping Physics lesson, Mr. P and the gang use gravitational potential energy to make sense of electric potential and electric potential energy. You’ll see how...

Pupil outcome: I can describe and apply the rules for voltage in a series circuit. Key learning points: - The voltage of a battery measures the strength with which it can ‘push’ current around a circuit. - The voltage of a component in...

Pupil outcome: I can describe how to measure voltage and the effect of different battery voltages on an electric circuit. Key learning points: - Voltage is a commonly used term for potential difference. - A voltmeter is used to measure...

Ready for action? Time to get your neurons firing with some action potential. If you thought resting potential was tough to understand, it seems like action potential is that much more difficult. However, thanks to Alie Astrocyte, we...

Voltage vs current, or sometimes it's current vs voltage; we are constantly trying to understand the differences between these two entities related to electricity. Then, there is sometimes one more entity: resistance. How do these three...

What is electricity? How is it created, and what makes it useful? Physics - Electricity And Circuits - Learning Points. Electricity is a flow of charge. The flow of moving electrons is known as the electric current. Voltage is the amount...

We use lemons and strips of zinc and copper to make a battery. First, strips of copper and zinc are added to one lemon and they are connected across a voltmeter. This is repeated, this time with more lemons and metal plates, until a...
