A Linear Variable Differential Transformer $($LVDT$)$ has two secondary coils A and B$.$ When the core is moved to be nearest to coil A the voltages induced will be: a the same in both coils b greater in coil A than in coil B

c greater in coil B than in coil A d reduced to zero $2.$ A Linear Variable Differential Transformer $($LVDT$)$ has its core centralized under the primary and the voltage induced in one of the secondary coils is $500$mV$.$ The voltage

induced in the other coil will be: a $250$mV aiding b $500$mV opposing c $500$mV aiding d $1\mathrm{.}0$V opposing

$3.$ A Linear Variable Differential Transformer $($LVDT$)$ has its core centralized under the primary and the voltage induced in one of the secondary coils is $500$mV$.$ The secondary

output voltage will be: a $0$V b $250$mV c $500$mV d $1\mathrm{.}0$V

$4.$ The output voltage of a Linear Variable Differential Transformer $($LVDT$)$ is taken to

a full$-$wave rectifier. As the core is moved through the LVDT from one end to the other

the output voltage of the full$-$wave rectifier will: a reverse polarity as the core passes through the central $($neutral$)$ position

b remain constant at all positions of the core

c gradually reduce from a maximum positive to zero

d reduce to minimum and then return to maximum positive again
