Free electrons seem to travel via the conductors with a certain degree of friction, or opposition to the motion. This opposition to the motion is more precisely known as resistance.
The amount of the current in a circuit relies on the concentration of voltage accessible to encourage the electrons, and also the amount of resistance in the circuit to oppose the flow of electron. Resistance to the flow of electrons in a conductor causes a loss of energy in the form of heat.
Well, if a students wants to determine the effects of fertilizer on corn growth, they could set up a experiment.
There would be two groups of corn each exposed to the same conditions. The only difference is that one of the groups is given fertilizer. The other isn’t, meaning that it is the control group.
