Answer:
The diagram shows a circuit with three identical lamps.The ammeter, A1, shows a reading of 1.5 A.
a) Indicate on the diagram where you would insert a switch so that it willswitch on or off lamps L2 and L3, but will not affect lamp L1.
b) What name is given to this arrangement of connecting lamps?
c) What will be the reading on ammeter A2?
d) What will be the reading on the voltmeter?

Step-by-step explanation:
x=2
2(2)^3-5(2)^2+a(2)+b=0
2*8-5*4+2a+b=0
16-20+2a+b=0
-4+2a+b=0
2a+b=4.......(I)
x=0
0-0+a*0+b=0
b=0
putting value of b in eqn.(I)
2a+b=4
2a+0=4
2a=4
a=2
hence a=2
b=0.
