Problem (1) The given Table gives the sets of observations obtained while studying the Townsend phenomenon in a gas. Compute: Set 1: Gap distance (mm) 05 1.0 1.5 2.0 2.5 3.0 35 4.0 Applied voltage 5.0 1000 2000 3000 4000 5000 6000 7000 8000 V (volts) 10000 Observed current (A) 10- 3 x 10-4 6x 10-15 10-12 4 x 10-12 10 5x 104 Set 2: V (volts) 500 .1000 1500 2000 2500 3000 3500 4000 4500 5 x 10- 1.5 x 10" 3 x 10" 6 x 10- 10- 5 x 10- 5 x 10- 3 x 10- 10 The minimum current observed when 150 V was applied was 5 x 10-" A. 10- 10- (A) • The electric field value E, for Set I. • The electric field value E2 for Set II. Townsend's primary ionization coefficient at E. (hint: draw curves)
• Townsend's primary ionization coefficient at E2. • Townsend's secondary ionization coefficient at E1. • Townsend's secondary ionization coefficient at E2.
