limonene-8,9-diol, and monohydroxylated limonene.8,10 About 25-30 percent of an oral dose of d-limonene in humans was found in urine as d-limonene-8,9-diol and its glucuronide; about 7-11 percent was eliminated as perillic acid and its metabolites.6 Safety D-limonene is considered to have fairly low toxicity.
In order to measure the voltage ,voltmeter should be connected in parallel. Voltmeter provides very high resistance . When voltmeter connected in parallel..so no current flowing through it due to very high resistance.. Voltage drop will occur..we get some voltage so its indicates voltage ( as per definition).
In order to convert a Galvanometer into voltmeter, a very high resistance known as series resistance is connected in series with the galvanometer. VALUE OF SERIES RESISTANCE www.citycollegiate.com Let resistance of galvanometer = Rg and resistance Rx (high) is connected in series to it. digital meter works by measuring volts so to use it as an ammeter, you connect it in parallel with a low resistance to measure the voltage dropped across the resistor that is relative to the current (ohms law again).
