The relation between the resistance of a circuit and the non-oscillatory condition is expressed as follows: If the resistance R is greater than 2 V p-. the circuit is non-oscilla-tory; if resistance is equal to 2 V the circuit is just oscillatory. If the resistance is less than 2 V ^the circuit will be oscillatory and will be suitable for the production of radio-frequency oscillation. In this equation R is expressed in ohms,

If the resistance is less than 2 V ^the circuit will be oscillatory and will be suitable for the production of radio-frequency oscillation. In this equation R is expressed in ohms, L in henries, and C in farads. The value of2 \J _- is seen to be the critical resistance to cause a given circuit to be non-oscillatory. The elements of a closed oscillation circuit in a radio-transmitter are connected togetherwith very heavy stranded copper wire or copper tubing which, excluding the resistance of thespark gap and other losses, tends to keep the resistance at a minimum; in fact, practical oscil-lation circuits do not have anywhere near the critical value of
