C = 1e-6 # Capacitance in farads

V = 5 # Voltage in volts

dt = 1e-6 # Time step in seconds

t_max = 0.01 # Total time in seconds

# Time array

t = np.arange(0, t_max, dt)

# Voltage array (initialize with zeros)

V_cap = np.zeros_like(t)

# Initial condition: Capacitor voltage is zero

V_cap[0] = 0

# Simulation loop

for i in range(1, len(t)):

dV = (V – V_cap[i-1]) / (R * C) * dt

V_cap[i] = V_cap[i-1] + dV

# Plot the results
