The current required by the 60W bulb is three-fifths that required by the 110W bulb
<h3>Electrical Power</h3>
- 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:
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

Answer:
the maximum angular speed (in radians per second) of a Blu-ray disc as it rotates is 57.6 m/s
Explanation:
Given information:
diameter of the disc, d = 11 cm, r = 5.5 cm = 0.055 m
angular speed ω = 10000 rev/min = (10000 rev/min)(2π rad/rev)(1/60 min/s)
= 1000π/3 rad/s
to calculate the maximum angular speed we can use the following formula
ω = v/r
v = ωr
= (1000π/3)(0.055)
= 57.6 m/s
Answer:
Vdc=10V
Explanation:
in a closed loop consisting of a super charged capacitor and an inductor, the super charge capacitor acts as a supply when the loop is closed, at t=0, the emf stored in the capacitor is 10V (q/c); and at that same time Vl= voltage across the inductor or loop too would be 10V,
if the loop remains closed for a longer period, the inductor would absorb energy from the capacitor till it dissipates all charges with itself.
