Final answer:
The correct option that represents voltage is b) Work done * charge. Voltage is the potential energy per unit charge and it is derived by multiplying the work done by the charge. For example, if we have a charge of 2 coulombs and a potential difference of 5 volts, the voltage can be calculated as 0.4 V.
Step-by-step explanation:
The correct option that represents voltage is b) Work done * charge.
Voltage is the potential energy per unit charge, which means that voltage has units of J/C (joules per coulomb). It is the amount of energy in a charge at a given potential. In the equation for electric power, P = IV, the value for voltage is derived from multiplying the work done (W) by the charge (Q).
For example, if we have a charge of 2 coulombs and a potential difference of 5 volts, the voltage can be calculated as V = W/Q = 2 J / 5 C = 0.4 V.
