6. WattCORRECT ANSWER The measurementof electricalwork done
7. Forms of ElectricityCORRECT ANSWER Staticand Dynamic
8. StaticElectricityCORRECT ANSWER (1) Electricityat rest


(2) Begins with a build up of eithera positiveor negativeelectroncharge.If two negativechargesor two positive charges
are brought close together, the objects that
hold that chargerepel each other.If a positivechargeis brought within close
proximity of a negative charge, the two objects attract each other



(3) Staticelectricityis producedby friction and is not easilymeasurednor is it controllable orusable
