physic

The heater element of a 120 V toaster is a nichrome wire with length 5.4 m and diameter 0.48 mm. The resistivity of nichrome at the operating temperature of the toaster is 1.3 times 10-6 Ohm m. The power drawn by the toaster is closed to: 370 W 360 W 380 W 400 W 410 W What happens to brightness of bulb C in the diagram when bulb D added in series to bulb A? Bulb C becomes brighter. Bulb C remains the same brightness. Bulb C becomes dimmer. Bulb C goes out (becomes completely dark). Cannot be determined without more information.

Explanation / Answer

power= 772.92 w = V^2/R BULB C BECOMES DIMMER AS VALTAGE ACROSS IT WILL REDUCE
