how do we do that?


Thanks

Hello Yasser!!

We reduce the heat loss in a circuit by:
1) lowering current
2) increasing R of variable resistor
3) adding another lamp
4) lowering voltage

and in the other one - use m (magnification) to get the values for the base(2 x m) and the height (1.5 x m). draw an inverted triangle and start from 2 cm and draw a line let and right. that 2 cm marks the centre of the base which will help you to draw the 3rd point using the height (1.5 x m)  :)

Study well!! Don't panic!!  ;)
