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)

LOT OF WORK is done to make more energy work
