is this a question or a full  question paper

ok i cananswer some shortt answers right now , others later


1 - conductor - objects which allow electric current to pass through them

2 - fuse - thin wire insidde the bulb

3 - insulators  -  objects which do not allow electric current to pass  through them

4 -  cell - the power source of te circuit

5 - current - flow of electrons

6 - electric circuit is a pah through which  current consists of wire , powersource (battery) , load and sometimes a switch..
