I would say both. Power (energy, or work, per unit time) can be calculated with the formula:

P = IV (power = current x voltage)

Q: Does current or voltage actually perform the work in a circuit?

Voltage x current = power (watts)

Current lags voltage in an inductive circuit. The angle by which it lags depends on the frequency of the AC, and on the relative size of the inductance compared to the resistance in the circuit.

The current (amps) will remain constant, but the voltage will drop.

That depends on the circuit - but note that in almost all real circuits the current is the dependent variable - you control the voltage and the current sets itself.

answer is actually voltage

Power (energy per time unit) actually depends on both. In a DC circuit, it is the product of voltage and current. In an AC circuit, it is the product of voltage x current x (power factor). The power factor is often close to 1.

Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)

Voltage attempts to make a current flow, and current will flow if the circuit is complete. It is possible to have voltage without current, but current cannot flow without voltage. The answer is "yes",voltage remains the same as current moves through the circuit.As the voltage remains constant, current increases in the circuit.

In this case current flows from a high voltage to a lower voltage in a circuit.

Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)

Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)

A voltage error circuit is called an error amplifier and happens when there are discrepancies between the voltage output and the reference voltage. A current error circuit happens when there is a disruption of flow in an ammeter.

Inductive. Voltage (E) leads current (I) in an inductive (L) circuit and current (I) leads voltage (E) in a capacitive (C) circuit. (ELI the ICEman)

Voltage leads current or, more specifically current lags voltage, in an inductive circuit. This is because an inductor resists a change in current.

The first thing you need to know is the internal resistance of the current source, the voltage source will have the same internal resistance. Then compute the open circuit voltage of the current source, this will be the voltage of the voltage source. You are now done.
