What does ICE stand for?

• A. Ice means Voltage leads Current in a Capacitive circuit.
• B. Ice stands for Current lagging voltage in a Capacitive circuit.
• C. Ice equals Current in a Resistive circuit leading Voltage.
• D. Current (I) in a capacitive circuit (C) leads voltage (E) by a max of 90 degrees

Answer: (D)

In a capacitor, the current relation to voltage has a lead: the current reaches its peak before the voltage does. That means the current leads the voltage by up to 90 degrees in an ideal capacitor (and by somewhat less in real circuits due to resistance and other factors). The statement you’re choosing captures this: the current in a capacitive circuit leads the voltage by as much as 90 degrees. This is different from a resistive circuit, where current and voltage are in phase, and different from an inductive circuit, where current lags the voltage. The ICE mnemonic helps you remember this: current leads voltage in a capacitor.
