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).
power lines image by Edsweb from Fotolia.com. A parallel circuit is an electrical circuit which has two or more paths for an electrical charge to flow through. The parallel circuit is the standard electrical circuit found in most homes and devices.Because it provides more than one way for a current to flow through to a device, it creates a much more stable and efficient power system than would otherwise be possible. The uses of the parallel circuit are manifold.arallel circuits are used inside many electrical devices and appliances. The main reason parallel circuitry is used in this context is to take advantage of more than one power source, like when more than one battery is being used in a portable device.
