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).
While ammeters are used to measure the currents, the voltmeter is used to measure the voltage. Both the devices are different in terms of functionality and circuit placement. An ammeter is an instrument that is used to measure the currents in a circuit.The currents are measured in amperes (A). Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters.ultimeters can also be utilized in place of both ammeters and voltmeters. A multimeter is an instrument that can be used to measure both, currents as well as voltages. It can also perform as ohmmeters, a device used to measure resistance. Multimeters are available in analog or digital format. Ammeter.
