Over the Counter Medications Drugs that are safe and effective for use by the general public without a prescription are defined as over-the-counter (OTC) drugs. These drugs are often located on shelves in pharmacies with easy access by patients, but may also be located in non-pharmacy outlets, such as grocery stores, convenience marts and large discount retailers.
Objects simply do not acquire charges on the order of 1.00 Coulomb. In fact, more likely Q values are on the order of 10-9 or possibly 10-6 Coulombs. For this reason, a Greek prefix is often used in front of the Coulomb as a unit of charge. Charge is often expressed in units of microCoulomb (ÂµC) and nanoCoulomb (nC).
The tesla (symbol T) is the SI derived unit of the strength of the magnetic field, commonly denoted as B. One tesla is equal to one weber per square metre, and it was named in 1960 in honour of Nikola Tesla.
