voltage x current x time?Advertisement
a) Wattage of bulb = voltage x current in ampere 60 W = 230 V x I I= 60/230 = .260 Amperes so .260 current flows throught the circut of the bulb for 2 hours - read more
In physics, power (symbol: P) is defined as the amount of energy consumed per unit time. In the MKS system, the unit of power is the joule per second (J/s), known as the watt (in honor of James Watt, the eighteenth-century developer of the steam engine). For example, the rate at which a light ... - read more
