. Electronic apparatus for biological research . Figure This property of jacks is extremely valuable in the metering of currents. To check a number of currents by having a separate meter for each is expensive and usually unnecessary. A better plan is to have one meter connected to a jack plug and break-in sockets in each of the circuits requiring measurement. One meter then serves for many. The same effect can, of course, be had by switching, but if the circuits in question are widely dispersed about the labora- tory the extra wiring required is considerable; the jack system is usually pr
