Answer :
To learn the viscosity and speed and resistance to calculate the diameter.
What is viscosity?
Viscosity is a fluid's (liquid or gas) resistance to a change in shape or motion of adjacent parts concerning one another. Viscosity indicates resistance to flow.
What constitutes speed?
The speed of a change in an object's position in any direction Speed is defined as the ratio of distance to the amount of time it takes to cover that distance. Since speed has only a direction and no magnitude, it is a scalar quantity.
Resistance AC circuit
in resistance AC circuit the voltage and current are related as,
Emf; E= EoSinωt
where, I_O=E_O/R
In purely resistive circuit, there is no phase change occurs. the phase angle between voltage and current is zero.
the maximum value of current is I_0 =v_0\R
if tha maximum volatge v_0 is increase with decrease of resistance R then current in the circuit will maximum and denoted asI_0
capacitive AC circuit
In capacitive AC circuit the voltage and current are related as,
Emf: E=E_Osinωt
and current I =I_Osinωt
⇒ I =I _0sin(ωt+π/2)
where,I_0 =E_0/X_C
in purely capacitive circuit, current leads the end by phase of π/2. the phase angle between volatge and current is π\2
The maximum value of current is,I_0 =E_0\X_C
if the maximum voltage E_0 is increases with decreases of capacitive X_c then current in the circuit will maxmium and denoted as I_0
when the emf is zero then current is maximum magnitude.so the current is maxmium before it leads or lag in the circuit.
inductive AC circuit:
Inductive AC circuit the voltage and current are related as
Emf: E= E_0sinωt
And current : I= (-)I_0cosωt
⇒ I= I_0sin(ωt -π/2)
where, Iπ_0 =E_0/X_L and x=∈L
In purely inductive circuit, the current lags behind the voltage (emf) by phase of π/2. The phase angle between volatge and current is π/2
The maximum value of current is, I_0 = E_0/X_L
if the maximum voltage E_0 is increase with decrease of inductive resistance X_L then current in the circuit will maximum and denoted is I_0.
Therefore, the emf is zero then current is maximum magnitude. so the current is maximum before it leads or lag in the circuit.
