Question

A 20.0-μF capacitor is charged to 200 V and is then connected across a 1000-Ω resistor. What is the initial current just after the capacitor is connected to the resistor

Answer 1

Answer:

i = 0.2 A

Explanation:

R = resistance of the resistor = 1000 Ω

V = Potential difference across the capacitor = Potential difference across the resistor = 200 V

i = initial current just after the capacitor is connected to resistor

Using ohm's law

$i = \frac{V}{R}$

Inserting the values

$i = \frac{200}{1000}$

i = 0.2 A
