Assignment Help Physics
Reference no: EM131321578

How many 30 watt lamps can you attach to a series circuit of four D-cell batteries (each at 1.5 volts) combined to deliver a current of 13 amperes?

(1. Find the resistance in each lamp; 2. Because resistances add in series, use Ohm's law for identical lamps to find the number of lamps.)
