What is the current through the lightbulb

Reference no: EM13282063

A typical lightbulb in your house is rated 200 W, which means that the bulb dissipates 200 W when connected to a DC voltage of 110 V.

(a) What is the current through the lightbulb?

(b) If the voltage is reduced to 55 V, what is the dissipated power?
