TermDefinition
Coulomb One coulomb is the amount of charge which flows past a point in a circuit in a time of 1 seconds when current is 1 A
Kirchhoff's First Law The sum of the currents entering any point in a circuit is equal to the sum of the currents leaving that same point
Electrical Current Flow of Charged Particles
Potential Difference Energy transferred per unit charge (V = W/Q)
Electromotive Force energy transferred from source/(changed from some form to electrical energy;) per unit charge (to drive charge round a complete circuit)
Ohm The ohm is the resistance of a component when a potential difference of 1 volt is produced per ampere of current.
Ohm's Law For a metallic conductor at constant temperature, the current in the conductor is directly proportional to the potential difference across its end
Progressive Force A progressive Force is one that transfers energy away from its source
Displacement Displacement is how far a point on a wave as moved from its undisturbed position.
Amplitude The maximum displacement from any point on the wave from its undisturbed position is the amplitude. Amplitude is measured in meters. Greater amplitude means louder sound or rougher sea.
Wavelength The distance from any point on a wave to the next exactly similar point (crest to crest) is the wavelength
Period T The time taken for one complete oscillation of a point in a wave is called the period T. It is the time taken for a point to move from one particle position and return to that same position (measured in seconds)
Frequency The number of oscillations per unit time of a point in a wave is called its frequency F. 1 Hz is one oscillation per second. F = 1/T
Phase difference The amount by which one wave lags behind another wave. Measured in degrees or radians.
Intensity Intensity is the rate of flow of energy per unit area at right angles to the direction of the wave measured in Wm-2 Intensity = amplitude^2

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
