  1. If a unit step current is passed through a capacitor what will be the voltage across the capacitor?
    1. 0
    2. A step function
    3. A ramp function
    4. An impulse function
Correct Option: C

Voltage across capacitor =
1
∫idt
C

= Integration of step input
= Ramp function
Hence, alternative (C) is the correct choice.
