From the Institute of Physics, these activities present a range of examples involving different types of charge carrier and links the measured current to rates of flow of charge. The activities consist of a series of demonstrations which could be set up before the lesson. These include: • considering different...

From the Institute of Physics, this learning episode shows that charge carriers in good conductors usually move very slowly. It illustrates the derivation and use of the equation I = nAvq.

A range of activities include:
• viewing the movement of permanganate ions in an electric field
•...

From the Institute of Physics, this learning episode provides a quantitative definition for resistance (R = V / I) which reinforces the qualitative notion that more resistance means less current. It looks at Ohm’s law, describing that this is not the same thing as the definition of resistance.

In these activities, from the Institute of Physics, the concept of electrical power is explored. Students find that the energy transferred by an electrical component depends on the potential difference, current and the time for which it operates.

From the Institute of Physics, this learning episode links Kirchhoff’s circuit laws to the conservation of charge and energy. Students can verify the laws experimentally and use them to solve simple circuit problems.

Produced by the Institute of Physics, this learning episode can be used to revises the idea of electromotive force (emf), introduce internal resistance and the consequent energy losses.

The activities include:
•...

Produced by the Institute of Physics, this learning episode helps students to distinguish alternating from direct currents before revising why alternating current (ac) is so important.

The range of activities include...

In this learning episode from the Institute of Physics, students are introduced to capacitors. Through practical investigations, students look at their charge and discharge process.

The activities include:
•...

Produced by the Institute of Physics, this learning episode looks at the energy stored in a capacitor. Students undertake a practical investigation to look at the energy stored and how this varies with potential difference and capacitance.

Produced by the Institute of Physics, this learning episode contains demonstrations and practical activities through which students learn about the conditions for static equilibrium (excluding moments of forces).

Students look at:
• forces on a horizontal washing line with a weight in the middle...

This learning episode, from the Institute of Physics, looks at the independence of vertical and horizontal motion. The crucial concept is that vertical acceleration does not affect horizontal velocity. This explains all projectile motion. There are a range of activities which include: • demonstrating and discussing...

Produced by the Institute of Physics, this learning episode considers the forces acting on a falling body in air and moves on to related experimental work.

The activities include:
• demonstrating the motion of...

This learning episode, from the Institute of Physics, looks at kinetic energy, work and velocity in relation to the braking distance of a vehicle. Two experiments are included, both of which connect work done in braking to the initial kinetic energy of the decelerating vehicle. The activities include: • discussion...

From the Institute of Physics, although concerned with conservation of mechanical energy, this episode extends the principle to its wider context in order to give the students a full appreciation of the overarching nature of the principle when they meet it in different situations. The activities include: •...

In this learning episode from the Institute of Physics, students use Hooke's law to demonstrate the strength and stiffness of materials when subject to linear tensile or compressive forces. The activities include: • recap of Hooke's law • explaining tension and extension in a variety of materials • explaining...
