If you double the voltage in a circuit and reduce the resistance by a factor of four, what will happen to the current?

a.)it will double
b.)it will decrease by factor of 2
c.)it will increase by a factor of 8
c.)it will decrease by a factor of 8

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
