What is difference between current transformer and potential transformer?

Question

Accepted Answer

Current transformer is used to measure current while potential transformer is used to measure voltage.

Current transformer is connected in series with the circuit being measured, while potential transformer is connected in parallel.
Current transformer steps down the current to a measurable level, while potential transformer steps down the voltage.
Current transformer is used for protection and metering purposes, while potential transformer is mainly used for metering and control.
Examples: Current transformer is used in power systems to measure high currents, while potential transformer is used in voltage measurement applications.
