by using Y-Y(Star) transformer..... bcoz in star VL = root 3* Vph

A transformer that increases voltage is a step-up transformer.
The thermocouple is an sesnsing device , when the temperature increases it increases the voltage , that voltage is used for tripping purpose
increases
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
A: Perfect example is a zener. As input voltage increases the current at the knee increases almost linearly at the zener voltage. If the inputs varies up or down then the current will vary up or down at the preset voltage making a zener a voltage regulator because of this feature
