Purely Resistive Circuit having a pure resistor ‘R’ connected across an A.C voltage source as shown in figure (1). Let the voltage applied to circuit be v.
Purely Inductive Circuit having a pure inductance ‘L’ connected across an A.C voltage source as shown in figure (1). Let the voltage applied to circuit be ‘v’.
“Maximum power transfer theorem states that the maximum power can be transferred from source (voltage source, current source) to the load only when the load resistance (RL) is equal to the internal resistance of the source (Ri)”. i.e, \[{{R}_{L}}={{R}_{i}}\]
The eddy current tachometer converts the angular speed (ω) of the rotor into pointer deflection ϕ. The diagram of the eddy current type tachometer is shown in figure 1. The eddy current tachometer is also referred as drag-up tachometer.
