The California Senate: The legislative body is accumulated of 40 members, with each member representing approximately 931,000 people. Due to the state's large population and relatively small legislature, the State Senate has the largest population per representative ratio of any state legislative house. In the United States House of Representatives, California is apportioned 53 representatives, each representing approximately 704,566 people, while in the State Senate, each of the 40 Senators represents approximately 931,349 people, with the result that California state senators each actually represent more voters than California's representatives to the United States Congress do. Each member roughly represents a population equivalent to the state of Delaware. As a result of Proposition 140 in 1990 and Proposition 28 in 2012, members elected to the legislature prior to 2012 are restricted by term limits to two four-year terms (eight years), while those elected in or after 2012 are allowed to serve 12 years in the legislature in any combination of four-year state senate or two-year state assembly terms.
The State Senate convenes at the California State Capitol in Sacramento.
In the current session, Democrats control 27 seats, comprising a two-thirds supermajority of the chamber. Republicans control 13 seats.https://en.wikipedia.org/wiki/California_State_Senate
The Vermont Senate: The Vermont Senate is the upper house of the Vermont General Assembly, the state legislature of Vermont. The Senate consists of 30 members. Senate districting divides the 30 members into three single-member districts, 62 member districts, 33 member districts, and one 6 member district.https://en.wikipedia.org/wiki/Vermont_Senate
Little about the U.S.A. Government: The number of representatives each state has is determined by the state's population. Larger states usually have more people and so they often have more representatives. However, the United States Constitution guarantees that each state will have at least one representative. https://www.reference.com/government-politics/states-representatives-other-states-4afd852eb11490d6#
ANSWER:So they have a different amount of Senate members because, Even though California is bigger it does not need as many Senate members to communicate the request of everyone in that state, Vermont has more due to the more opinions of the people in their state.
HOPE THIS HELPS :)
