Meiosis produces 4 haploid cells. Mitosis produces 2 diploid cells. The old name for meiosis was reduction/ division. Meiosis I reduces the ploidy level from 2n to n (reduction) while Meiosis II divides the remaining set of chromosomes in a mitosis-like process (division).itosis produces 2 diploid cells.

Pilot Duty Ratings. A Relay can be assigned a Pilot Duty Rating when it is used for switching loads on another relay, or solenoid valve coils. It can be a direct current (DC) rating, or an alternating current (AC) rating, as shown in the table at the bottom of this post. The Pilot Duty Ratings are obtained after performing product qualification tests.
A type of relay that can handle the high power required to directly control an electric motor or other loads is called a contactor. Solid-state relays control power circuits with no moving parts, instead using a semiconductor device to perform switching.
