What would be the relative difference between the currents required by a 60W lightbulb and a
100W lightbulb?

The current required by the 60W bulb is three-fifths that required by the 110W bulb

Electrical Power

  • Electrical power is defined as the amount of electrical work done per second
  • Power = electrical work done in joules/time taken in seconds

The formula for calculating power is as follows:

  • P = IV = V²/R = I²R

Assuming the voltage across the light bulbs is the same

From the formula, P = IV;

I = P/V

For the 60 W bulb

I₁ = 60/V

For the 100W bulb

I₂ = 100/V

Taking ratios of the currents:

I₁/I₂ = {60/V}/{`100/V}

I₁/I₂ = 3/5

Therefore, the current required by the 60W bulb is three-fifths that required by the 110W bulb
