first you take four lemons. Then roll them around until they become sort of soft. Then stick a copper nail or penny and a zinc nail into each lemon. Then take wires and connect each wire to one zinc nail and one copper nail. finally take a wire that is only touching copper and one that is only touching zinc and connect it to the light bulb and it should turn on.
try to make a path of circuit
That is impossible.
try using a 555 circuit
24-to1mux circuit
using it in a battery
a grapes is a fruit..........
heres an example." I bulit a science circuit today"said Tommy
Using tracks of metal such as on a PCB (printed circuit board) or using other electrically conductive material such as the graphite in 'lead' pencils.
make a electric circuit,by using resistors,cll then electricity is produced.
The disadvantage of using a voltmeter and ammeter on circuit measurements is that internal burden in both these instruments can affect circuit operation so much as to make a measurement useless.
By using Thevenin's theorem we can make a complex circuit into a simple circuit with a voltage source(Vth) in series with a resistance(Rth)
Circuit continuity can be tested by using an ohm meter.
