a. For the circuit shown in Figure 1, the switch is at position #1 for an extended period. Given that the switch is moved to position #2 at time t = 0, calculate the current flowing through the 4 ks2 resistor for t> 0 20 VV, 1=0 8kQ ww R₁ C 200 µF R₂ Figure #1 ww 4 ΚΩ

The resistance R and a 2 μF capacitor are connected in series across 200-V dc supply. Across the capacitor is a neon lamp that strikes at 120 volts. Calculate the value of R to make the lamp strikes 5 seconds after the switch has been closed.

What is the value of the R to get the full deflection??
