Circuits
Identify these circuit symbols:
bulb throw switch voltmeter fuse ammeter battery cell resistor
push switch Light dependent resistor loudspeaker diode thermistor battery cell variable resistor
Link up these devises with the job they do:
Cell or battery
Converts electrical energy into movement Converts electrical energy into sound energy Converts chemical energy into electrical energy Resistance increases as light level decreses Resistance increases as temperature decreases
Loudspeaker
Thermistor
Light dependent resistor
Motor
Variable resistor
It has a fixed value, measured in Ohms Has a thin wire that breaks if the current is too high Measures the potential difference or the Voltage Lets electricity flow through it in one direction only Measures the current in Amperes Adjusted to alter the current in a circuit
Diode
It has a fixed value, measured in Ohms Has a thin wire that breaks if the current is too high Measures the potential difference or the Voltage Lets electricity flow through it in one direction only Measures the current in series Adjusted to alter the current in a circuit
Resistor
Fuse
Ammeter
Voltmeter
It has a fixed value, measured in Ohms Has a thin wire that breaks if the current is too high Measures the Voltage in parallel Lets electricity flow through it in one direction only Measures the current in series Adjusted to alter the current in a circuit
