A resistor and a capacitor are connected in series to an ideal battery of constant terminal voltage. When the system reaches its steady state, what is the voltage across the resistor and the capacitor? A resistor and a capacitor are connected in series to an ideal battery of constant terminal voltage. When the system reaches its steady state, what is the voltage across the resistor and the capacitor? The voltage across the resistor is equal to the terminal voltage of the battery, and the voltage across the capacitor is zero. The voltage across both the resistor and the capacitor is equal to the terminal voltage of the battery. The voltage across both the resistor and the capacitor is zero.
