Connect 4 Change the terms in the following template to customize Connect 4 for any topic. You will need to copy one copy of one of the two templates (this is the game board) and two different colored copies of the second template page (these will be cut out to make the colored chips played by each player).

Can be used to vary the brightness of a bulb A circuit constructed from 4 diodes Increases the length of the resistance wire in a rheostat Used to decrease voltage An electrical device that stores charge temporarily A potential divider circuit with a thermistor can be used as a Used to isolate the low voltage in the sensing circuit from high mains voltage Full-wave rectification Resistance = Resistance of this component decreases with increasing light intensity Transformer with the same number of turns on the primary and secondary coils Half-wave rectification The circuit diagram for an AND gate Transformer with more turns on the secondary coil than the primary coil The equation for calculating the total resistance for resistors in series Circuit showing how an NPN transistor can be used as a switch for an LED Resistance of this component decreases with increasing temperature Used to predict the direction of the force on a current-carrying wire The equation for calculating the total resistance for resistors in parallel Circuit diagram for an NPN transistor Contains two different layers, a p-type layer and an n-type layer Used as switches in electronic components such as computer chips Potential divider circuit Generating an electric current by moving a magnet near a wire
