describe an activity to show that thermoplastic is a poor conductor of electricity
Answers
Aim: To show thermoplastic is a poor conductor of electricity.
Materials required: A battery, conducting copper wires, an LED bulb, a small PVC (thermoplastic) rod, a metal rod.
Experiment: We make a circuit as shown. First, we connect the two ends of the copper wires with the metal rod. Next, we replace it with the PVC rod.
Observation: The LED bulb glows when the metal rod is connected but does not glow when the PVC rod is connected.
Conclusion: Thermoplastic is a poor conductor of electricity.
Answer:
THERMOPLASTIC IS POOR CONDUCTOR OF HEAT and ELECTRICITY. IT IS SOFT AND BEND EASILY.
OK NOW, ACTIVITY
TAKE A BATTERY,BULB AND WIRE AND A PIEACE OF THERMOPLASTIC like:- acrylic, polyester, polypropylene, polystyrene, nylon and Teflon.
MAKE A CIRCUIT IN WHICH THERMO PLASTIC BEHAVES LIKE SWITCH.
MEAN TO SAY CONNECT ONE WIRE OF BATTERY AND BULB WITH Thermoplastic
AND U WILL OBSERVE THE BULB WILL NOT GLOW.
