🔍 Key Concepts

• Energy and time relationship in ignition systems (power is energy over time) • Purpose of a spark in a gas turbine: to reliably ignite the fuel‑air mixture during start • Effect of high energy vs. low energy and short vs. long duration on spark intensity

💭 Think About

• Think about what kind of spark is needed to jump the plug gap and ignite a high‑velocity, high‑pressure fuel‑air mixture in a turbine combustor: should it be brief and intense, or long and weak? • If you keep the same total energy but spread it over a longer time, what happens to the peak power (spark intensity)? • In a marginal ignition environment (poor atomization, low temperature, high airflow), which combination of energy and time gives the strongest, most reliable ignition kernel?

✅ Before You Answer

• Compare maximum vs. minimum energy first: which is more likely to give a strong, reliable spark? • Then compare maximum vs. minimum time: for the same energy, which gives higher instantaneous power (energy per unit time)? • Eliminate the options that obviously describe a weak, low-intensity spark, since that would not be called "optimum" for turbine ignition.
