Okay. I'm willing to do that. But first you'll have to tell me something about the sample in question 3.
answer:
1.When an electric current is passed through a conductor, the conductor becomes hot after some time and produce heat. This happens due to the conversion of some electric energy passing through the conductor into heat energy. This effect of electric current is called heating effect of current.
2.As per the law of combination of resistances in series,
R=R1 +R2 +R3+R4+R5
R=0.2+0.2+0.2+0.2+0.2
=1ohm
3.power is amount of electrical energy consumed per unit time. Amount of power consumed in a device is proportional to the current flowing in the device. The unit of electric power is watt.
A waves frequency (in Hertz) is how many crests pass by a point per second. easily confused with period, which is the amount of time it takes for a full wave to pass by a certain point
