The bulb’s resistance may be estimated using the formula.
V2/R1 = P1
V2/P1 = R1
We obtain by substituting the values.
x=110
As a result, 110 lights may be linked in series.
Several electric bulbs designed to be used on a 220 V electric supply line, are rated 10 W. How many lamps can be connected in parallel with each other across the two wires of 220 V line if the maximum allowable current is 5 A?
