Lowers Recommended Lead-Level Limits in Children. For the first time in 20 years, federal health authorities have lowered the recommended limit for lead exposure in young children, which they say could add 200,000 children to those believed to have unsafe lead levels in their blood.
Electrical Units of Measure. The standard SI units used for the measurement of voltage, current and resistance are the Volt [ V ], Ampere [ A ] and Ohm [ Ï ] respectively.
home / study / engineering / electrical engineering definitions / electromotive force. The standard unit of electromotive force (EMF) is the volt. Engineers abbreviate the word âvoltâ or âvoltsâ as V. An EMF of 1 volt (1 V) across a component with a resistance of 1 ohm drives a current of 1A through that component. If the term âelectromotive forceâ seems esoteric, think of it as âelectrical pressure.â Most people call it voltage.
