P2- TOPIC 2 : CONTROLLING AND USING ELECTRIC CURRENT
Cards in this deck (17)
- 1WHERE CAN AN AMMETER BE PLACED IN A SERIES CIRCUITANYWHERE
- 2ELECTRONS ARE NOT ...USED UP
THE CURRENT LEAVING THE POWER PACK IS THE SAME A WHAT COMES IN - 3EXPLAIN THIS PICTUREHERE THE AMMETER MUST BE PLACED IN A CERTAIN PLACE AS THE CURRENT CHANGE WHEN IT REACHES A JUNCTION
THREE AMMETERS ARE IN THIS AS A1 SHOULD BE EQUAL TO A2 + A3 AS THE CURRENT SPLITS AT THE JUNCTION - 4WHAT IS THE POTENTIAL DIFFERENCEANOTER WORD FOR VOLTAGE THE DIFFERENCE IN ELECTRON BEFORE AND AFTER THEY HAVE FLOWED THROUGH THE CIRCUIT
- 5WHAT IS ONE WAY TO CHANGE THE CURRENT OF THE CIRCUITCHANGE THE VOLTAGE
- 6THE HIGHER THE _______ THE HIGER THE _________VOLTAGE
CURRENT - 7HOW DO YOU MESURE THE POTENTIAL DIFFERENCEWITH A VOLMETER
- 8WHERE WOULD YOU PLACE THIS IN THE CIRCUITIN PARALLEL WITH THE COMPONENT
- 9WHAT DOES POTENTIAL DIFFERENCE MEASURETHE ENERGY TRANSFERRED TO A COMPONENT FOR EACH UNIT OF CHARGE THAT PASSES THROUGH IT
- 10WHAT IS THE SYMBOL FOR RESISTANCEOHMS
- 11CHANGING THE RESISTANCE IN A CIRCUIT CHANGES THE WHAT ?CURRENT
- 12NAME THE SYMBOLDIODE - CURRENT ONLY FLOWS IN ONE DIRECTION
- 13—LDR LIGHT DEPENDENT RESISTOR
MORE LIGHT = LESS RESISTANCE
- 14—THERMISTOR HIGHER RESISTANCE WHEN COLD
- 15EXPLAIN WHAT A VARIABLE RESISTOR DOESCHANGES THE CURRENT OF A CIRCUIT BY MANUALLY CHANGING THE RESISTANCE
- 16EXPLAIN THE SYMBOLS V = I x RPOTENTIAL DIFFERENCE
CURRENT
RESISTANCE - 17WHAT HAPPENS TO THE RESISTANCE OF A FILAMENT LAMPTHE HIGHER THE POTENTIAL DIFFERENCE MAKES THE LAMP HOTTER INCREASING THE RESISTANCE
