An increase in light intensity causes an increase in electric current.
The rate of electron passage in a conductor is known as electric current. The ampere is the electric current's SI unit. Electrons are little particles that are part of a substance's molecular structure. These electrons can be held loosely or securely depending on the situation.
Electric current is measured in a SI unit known as an ampere, or A. It is determined by assuming that the elementary charge, e, has a fixed numerical value of 1.602 176 634 x 10-19 when expressed in unit C, which is equivalent to the second in terms of VCs.
