How much power is dissipated by a light bulb if its applied voltage is 12 V and its resistance is 12 Ω?

If the circuit is constructed with a 12 V power supply and a 5.1 Ω light bulb as a resistor, how much current flows through the circuit?

A simple circuit contains a 10 V battery connected with wires to a small bulb. If the power dissipated by the bulb is 0.5 W, what is the resistance of the bulb?Remember to identify all data (givens and unknowns), list equations used, show all your work, and include units and the proper number of significant digits to receive full credit.

When an electric lamp is connected to 12V battery, it draws a current 0.5A. Find the power of the lamp.

A 6O-W, 120-V light bulb is to be connected in series with a resistor across a 277-V line. What is the resistanceand minimum power rating of the resistor required if the light bulb is to operate under rated conditions?

The hot resistance of a 240 V filament lamp is 960Ω. Find the current taken by the lamp and its power rating
