3. varistor
   varistor In electricity, a variable resistor. A two-electrode resistor made of semiconductor material and having voltage-dependent nonlinear resistance which drops with an increase in applied voltage; can be used to protect sensitive equipment from power spikes or lightning strikes by shunting the energy to the ground.

5. Varistor
   A varistor is an electronic component with a "diode-like" nonlinear current–voltage characteristic. The name is a portmanteau of variable resistor. Varistors are often used to protect circuits against excessive transient voltages by incorporating them into the circuit in such a way that, when tri...
