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).
An ammeter measures current; a voltmeter measures the voltage between two points; and an ohmmeter measures resistance. A multimeter combines these functions into a single instrument. A multimeter can be used to measure voltage, current and resistance in an electrical circuit that uses resistors and capacitors. To understand how to use a multimeter with these components, schematic symbols for resistors, capacitors and other electronic schematic symbols need to be readily recognized.
