In electrical work, the symbol W is used to indicate a. voltage. b. resistance. c. electromagnetic force. d. current.
The question has no answer, sad to say. The symbol W is used as a shortcut of saying "watts" which refers to the unit of power. The symbol for Voltage = V The symbol for resistance = R (unit is Ohms) The symbol of electromagnetic force = N (for Newton) The symbol or current = I (unit is A for amperes)
