What happens if you connect a capacitor without a resistor?

Without a load, current will not flow through a circuit, and will thus not charge a capacitor in the circuit. Instead of using a resistor as a load in order to charge a capacitor, any other load can be implemented.

What happened in a RC circuit if R is made equal to zero?

RC approaches zero as R approaches zero. As the time constant approaches zero a capacitor with no resistance will charge and discharge very quickly. You can see this quite clearly in the series expansion for the exponential function. The leading term is 1 and the rest of the terms disappear.

What happens to a capacitor when it is connected to a battery?

Capacitors store energy by holding apart pairs of opposite charges. If you attach a capacitor (with capacitance C) to a battery (at voltage V), it will slowly develop a charge on each plate ( Q) as electrons build up on one plate and then exit the other.

What happens when capacitor is zero?

Capacitors are charged through a resistor. Initially, when the charge is zero, the potential across the capacitor is zero. Hence maximum current flows through the circuit. As the potential builds up , the current reduces.

Why are resistors used with capacitors?

When capacitors and resistors are connected together the resistor resists the flow of current that can charge or discharge the capacitor. The larger the resistor , the slower the charge/discharge rate. The larger the capacitor , the slower the charge/discharge rate.

What is a capacitor with 0 capacitance?

Zero capacitance means zero accumulation of electrical charge on the capacitor plates or conductors. Can a potential difference or voltage still exist between the capacitor plates or conductors in the absence of electrical charges? Yes. Happens all the time.

How does a capacitor affect a circuit?

Thus, a capacitor lets more current flow as the frequency of the source voltage is increased. The apparent resistance of a capacitor in an AC circuit is less than its DC resistance. This apparent AC resistance is called capacitive reactance, and its value decreases as the applied frequency increases.
